 The compute() method is equivalent to calling both analyzePattern() and factorize().
 
-Finally, each solver provides some specific features, such as determinant, access to the factors, controls of the iterations, and so on.

 \section TheSparseCompute The Compute Step
 In the compute() function, the matrix is generally factorized: LLT for self-adjoint matrices, LDLT for general hermitian matrices, LU for non hermitian matrices and QR for rectangular matrices. These are the results of using direct solvers. For this class of solvers precisely, the compute step is further subdivided into analyzePattern() and factorize().
