This function works in full - * generality, for points in a space of arbitrary dimension, and also over - * the complex numbers, but for this example we will work in dimension 3 - * over the real numbers (doubles). - * - * So let us work with the following set of 5 points given by their - * \f$(x,y,z)\f$ coordinates: - * @code - Vector3d points[5]; - points[0] = Vector3d( 3.02, 6.89, -4.32 ); - points[1] = Vector3d( 2.01, 5.39, -3.79 ); - points[2] = Vector3d( 2.41, 6.01, -4.01 ); - points[3] = Vector3d( 2.09, 5.55, -3.86 ); - points[4] = Vector3d( 2.58, 6.32, -4.10 ); - * @endcode - * Suppose that we want to express the second coordinate (\f$y\f$) as a linear - * expression in \f$x\f$ and \f$z\f$, that is, - * \f[ y=ax+bz+c \f] - * for some constants \f$a,b,c\f$. Thus, we want to find the best possible - * constants \f$a,b,c\f$ so that the plane of equation \f$y=ax+bz+c\f$ fits - * best the five above points.

Let us check for - * instance how near points[0] is from the plane of equation \f$y=ax+bz+c\f$. - * Looking at the coords of points[0], we see that: - * \f[ax+bz+c = 0.495 * 3.02 + (-1.927) * (-4.32) + (-2.906) = 6.91.\f] - * On the other hand, we have \f$y=6.89\f$. We see that the values - * \f$6.91\f$ and \f$6.89\f$ - * are near, so points[0] is very near the plane of equation \f$y=ax+bz+c\f$. - * - * Let's now describe precisely the parameters: - * @param numPoints the number of points - * @param points the array of pointers to the points on which to perform the linear regression - * @param result pointer to the vector in which to store the result. - This vector must be of the same type and size as the - data points. The meaning of its coords is as follows. - For brevity, let \f$n=Size\f$, - \f$r_i=result[i]\f$, - and \f$f=funcOfOthers\f$.

In particular, it can be composed - * with any other transformations (Transform,Translation,RotationBase,Matrix) - * and can be directly used to transform implicit homogeneous vectors.

For the composition of transformations, - * its principle consists to first convert the right/left hand sides of the product - * to a compatible (Dim+1)^2 matrix and then perform a pure matrix product. - * Of course, internally, operator* tries to perform the minimal number of operations - * according to the nature of each terms. Likewise, when applying the transform - * to non homogeneous vectors, the latters are automatically promoted to homogeneous - * one before doing the matrix product. The convertions to homogeneous representations - * are performed as follow: - * - * \b Translation t (Dim)x(1): - * \f$ \left( \begin{array}{cc} - * I & t \\ - * 0\,...\,0 & 1 - * \end{array} \right) \f$ - * - * \b Rotation R (Dim)x(Dim): - * \f$ \left( \begin{array}{cc} - * R & 0\\ - * 0\,...\,0 & 1 - * \end{array} \right) \f$ - * - * \b Linear \b Matrix L (Dim)x(Dim): - * \f$ \left( \begin{array}{cc} - * L & 0\\ - * 0\,...\,0 & 1 - * \end{array} \right) \f$ - * - * \b Affine \b Matrix A (Dim)x(Dim+1): - * \f$ \left( \begin{array}{c} - * A\\ - * 0\,...\,0\,1 - * \end{array} \right) \f$ - * - * \b Column \b vector v (Dim)x(1): - * \f$ \left( \begin{array}{c} - * v\\ - * 1 - * \end{array} \right) \f$ - * - * \b Set \b of \b column \b vectors V1...Vn (Dim)x(n): - * \f$ \left( \begin{array}{ccc} - * v_1 & ... & v_n\\ - * 1 & ... & 1 - * \end{array} \right) \f$ - * - * The concatenation of a Transform object with any kind of other transformation - * always returns a Transform object. - * - * A little exception to the "as pure matrix product" rule is the case of the - * transformation of non homogeneous vectors by an affine transformation. In - * that case the last matrix row can be ignored, and the product returns non - * homogeneous vectors. - * - * Since, for instance, a Dim x Dim matrix is interpreted as a linear transformation, - * it is not possible to directly transform Dim vectors stored in a Dim x Dim matrix. - * The solution is either to use a Dim x Dynamic matrix or explicitly request a - * vector transformation by making the vector homogeneous: - * \code - * m' = T * m.colwise().homogeneous(); - * \endcode - * Note that there is zero overhead. - * - * Conversion methods from/to Qt's QMatrix and QTransform are available if the - * preprocessor token EIGEN_QT_SUPPORT is defined. - * - * This class can be extended with the help of the plugin mechanism described on the page - * \ref TopicCustomizingEigen by defining the preprocessor symbol \c EIGEN_TRANSFORM_PLUGIN. - * - * \sa class Matrix, class Quaternion - */ -template<typename _Scalar, int _Dim, int _Mode, int _Options> -class Transform -{ -public: - EIGEN_MAKE_ALIGNED_OPERATOR_NEW_IF_VECTORIZABLE_FIXED_SIZE(_Scalar,_Dim==Dynamic ?

See discussion of possible values below. - * - * SVD decomposition consists in decomposing any n-by-p matrix \a A as a product - * \f[ A = U S V^* \f] - * where \a U is a n-by-n unitary, \a V is a p-by-p unitary, and \a S is a n-by-p real positive matrix which is zero outside of its main diagonal; - * the diagonal entries of S are known as the \em singular \em values of \a A and the columns of \a U and \a V are known as the left - * and right \em singular \em vectors of \a A respectively. - * - * Singular values are always sorted in decreasing order. - * - * This JacobiSVD decomposition computes only the singular values by default. If you want \a U or \a V, you need to ask for them explicitly. - * - * You can ask for only \em thin \a U or \a V to be computed, meaning the following. In case of a rectangular n-by-p matrix, letting \a m be the - * smaller value among \a n and \a p, there are only \a m singular vectors; the remaining columns of \a U and \a V do not correspond to actual - * singular vectors. Asking for \em thin \a U or \a V means asking for only their \a m first columns to be formed. So \a U is then a n-by-m matrix, - * and \a V is then a p-by-m matrix. Notice that thin \a U and \a V are all you need for (least squares) solving. - * - * Here's an example demonstrating basic usage: - * \include JacobiSVD_basic.cpp - * Output: \verbinclude JacobiSVD_basic.out - * - * This JacobiSVD class is a two-sided Jacobi R-SVD decomposition, ensuring optimal reliability and accuracy. The downside is that it's slower than - * bidiagonalizing SVD algorithms for large square matrices; however its complexity is still \f$ O(n^2p) \f$ where \a n is the smaller dimension and - * \a p is the greater dimension, meaning that it is still of the same order of complexity as the faster bidiagonalizing R-SVD algorithms. - * In particular, like any R-SVD, it takes advantage of non-squareness in that its complexity is only linear in the greater dimension. - * - * If the input matrix has inf or nan coefficients, the result of the computation is undefined, but the computation is guaranteed to - * terminate in finite (and reasonable) time. - * - * The possible values for QRPreconditioner are: - * \li ColPivHouseholderQRPreconditioner is the default. In practice it's very safe. It uses column-pivoting QR. - * \li FullPivHouseholderQRPreconditioner, is the safest and slowest. It uses full-pivoting QR. - * Contrary to other QRs, it doesn't allow computing thin unitaries. - * \li HouseholderQRPreconditioner is the fastest, and less safe and accurate than the pivoting variants. It uses non-pivoting QR. - * This is very similar in safety and accuracy to the bidiagonalization process used by bidiagonalizing SVD algorithms (since bidiagonalization - * is inherently non-pivoting). However the resulting SVD is still more reliable than bidiagonalizing SVDs because the Jacobi-based iterarive - * process is more reliable than the optimized bidiagonal SVD iterations. - * \li NoQRPreconditioner allows not to use a QR preconditioner at all. This is useful if you know that you will only be computing - * JacobiSVD decompositions of square matrices. Non-square matrices require a QR preconditioner. Using this option will result in - * faster compilation and smaller executable code. It won't significantly speed up computation, since JacobiSVD is always checking - * if QR preconditioning is needed before applying it anyway. - * - * \sa MatrixBase::jacobiSvd() - */ -template<typename _MatrixType, int QRPreconditioner> class JacobiSVD -{ - public: - - typedef _MatrixType MatrixType; - typedef typename MatrixType::Scalar Scalar; - typedef typename NumTraits<typename MatrixType::Scalar>::Real RealScalar; - typedef typename MatrixType::Index Index; - enum { - RowsAtCompileTime = MatrixType::RowsAtCompileTime, - ColsAtCompileTime = MatrixType::ColsAtCompileTime, - DiagSizeAtCompileTime = EIGEN_SIZE_MIN_PREFER_DYNAMIC(RowsAtCompileTime,ColsAtCompileTime), - MaxRowsAtCompileTime = MatrixType::MaxRowsAtCompileTime, - MaxColsAtCompileTime = MatrixType::MaxColsAtCompileTime, - MaxDiagSizeAtCompileTime = EIGEN_SIZE_MIN_PREFER_FIXED(MaxRowsAtCompileTime,MaxColsAtCompileTime), - MatrixOptions = MatrixType::Options - }; - - typedef Matrix<Scalar, RowsAtCompileTime, RowsAtCompileTime, - MatrixOptions, MaxRowsAtCompileTime, MaxRowsAtCompileTime> - MatrixUType; - typedef Matrix<Scalar, ColsAtCompileTime, ColsAtCompileTime, - MatrixOptions, MaxColsAtCompileTime, MaxColsAtCompileTime> - MatrixVType; - typedef typename internal::plain_diag_type<MatrixType, RealScalar>::type SingularValuesType; - typedef typename internal::plain_row_type<MatrixType>::type RowType; - typedef typename internal::plain_col_type<MatrixType>::type ColType; - typedef Matrix<Scalar, DiagSizeAtCompileTime, DiagSizeAtCompileTime, - MatrixOptions, MaxDiagSizeAtCompileTime, MaxDiagSizeAtCompileTime> - WorkMatrixType; - - /** \brief Default Constructor. - * - * The default constructor is useful in cases in which the user intends to - * perform decompositions via JacobiSVD::compute(const MatrixType&). - */ - JacobiSVD() - : m_isInitialized(false), - m_isAllocated(false), - m_usePrescribedThreshold(false), - m_computationOptions(0), - m_rows(-1), m_cols(-1), m_diagSize(0) - {} - - - /** \brief Default Constructor with memory preallocation - * - * Like the default constructor but with preallocation of the internal data - * according to the specified problem size. - * \sa JacobiSVD() - */ - JacobiSVD(Index rows, Index cols, unsigned int computationOptions = 0) - : m_isInitialized(false), - m_isAllocated(false), - m_usePrescribedThreshold(false), - m_computationOptions(0), - m_rows(-1), m_cols(-1) - { - allocate(rows, cols, computationOptions); - } - - /** \brief Constructor performing the decomposition of given matrix. - * - * \param matrix the matrix to decompose - * \param computationOptions optional parameter allowing to specify if you want full or thin U or V unitaries to be computed. - * By default, none is computed.

It handles transparently real - * and complex arithmetics with single and double precision, depending on the - * scalar type of your input matrix. - * The code has been optimized to provide BLAS-3 operations during supernode-panel updates. - * It benefits directly from the built-in high-performant Eigen BLAS routines. - * Moreover, when the size of a supernode is very small, the BLAS calls are avoided to - * enable a better optimization from the compiler.

It is used to reorder the columns - * (and eventually the rows) of the matrix to reduce the number of new elements that are created during - * numerical factorization.
