Detailed Description

template<typename Value_T>
class LinAlg::Matrix< Value_T >

Dense matrix.

Note: The values are internally saved in Column-Major order, thus, the method GetPtr() may be passed to a FORTRAN-style routine with no problems.

Examples:

• tmv.cpp Test matrix-vector multiplication
• tsv.cpp Test LAPACK solver
• tsymmv.cpp Test symmetric matrix-vector multiplication
