Classes
class	strumpack::DenseMatrix< scalar_t >
	This class represents a matrix, stored in column major format, to allow direct use of BLAS/LAPACK routines. More...
class	strumpack::DenseMatrixWrapper< scalar_t >
	Like DenseMatrix, this class represents a matrix, stored in column major format, to allow direct use of BLAS/LAPACK routines. However, objects of the DenseMatrixWrapper class do not allocate, own or free any data. More...
