Such problem can be mathematically expressed as a linear problem of the form \f$ Ax=b \f$ where \f$ x \f$ is the vector of \c m unknowns (in our case, the values of the pixels), \f$ b \f$ is the right hand side vector resulting from the boundary conditions, and \f$ A \f$ is an \f$ m \times m \f$ matrix containing only a few non-zero elements resulting from the discretization of the Laplacian operator. <table class="manual"> diff --git a/doc/special_examples/CMakeLists.txt b/doc/special_examples/CMakeLists.txt index 138a2f6ef..0c9b3c3ba 100644 --- a/doc/special_examples/CMakeLists.txt +++ b/doc/special_examples/CMakeLists.txt @@ -10,12 +10,12 @@ endif(NOT EIGEN_TEST_NOQT) if(QT4_FOUND) add_executable(Tutorial_sparse_example Tutorial_sparse_example.cpp Tutorial_sparse_example_details.cpp) target_link_libraries(Tutorial_sparse_example ${EIGEN_STANDARD_LIBRARIES_TO_LINK_TO} ${QT_QTCORE_LIBRARY} ${QT_QTGUI_LIBRARY}) - + add_custom_command( TARGET Tutorial_sparse_example POST_BUILD - COMMAND Tutorial_sparse_example - ARGS ${CMAKE_CURRENT_BINARY_DIR}/../html/Tutorial_sparse_example.jpeg + COMMAND Tutorial_sparse_example ARGS ${CMAKE_CURRENT_BINARY_DIR}/../html/Tutorial_sparse_example.jpeg ) + add_dependencies(all_examples Tutorial_sparse_example) endif(QT4_FOUND) diff --git a/doc/special_examples/Tutorial_sparse_example_details.cpp b/doc/special_examples/Tutorial_sparse_example_details.cpp index 8c3020b63..7d820b44a 100644 --- a/doc/special_examples/Tutorial_sparse_example_details.cpp +++ b/doc/special_examples/Tutorial_sparse_example_details.cpp @@ -11,8 +11,8 @@ void insertCoefficient(int id, int i, int j, double w, std::vector<T>& coeffs, int n = boundary.size(); int id1 = i+j*n; - if(i==-1 || i==n) b(id) -= w * boundary(j); // constrained coeffcieint - else if(j==-1 || j==n) b(id) -= w * boundary(i); // constrained coeffcieint + if(i==-1 || i==n) b(id) -= w * boundary(j); // constrained coefficient + else if(j==-1 || j==n) b(id) -= w * boundary(i); // constrained coefficient else coeffs.push_back(T(id,id1,w)); // unknown coefficient } |
