Functions
template<typename T>
int_t	belfem::lapack::leading_dimension (const Vector< T > &A)
	logical length of a vector operand, as passed to LAPACK as LDB; vector storage is contiguous under both backends
template<typename T>
int_t	belfem::lapack::leading_dimension (const Matrix< T > &A)
	stride between the columns of an owning, column-major matrix, as passed to LAPACK as LDA/LDB/LDC.
int_t	belfem::lapack::work_size (const float &aValue)
	lapack reports the optimal work size in the first entry of the work array, which stays real valued for the complex flavors
int_t	belfem::lapack::work_size (const double &aValue)
int_t	belfem::lapack::work_size (const std::complex< float > &aValue)
int_t	belfem::lapack::work_size (const std::complex< double > &aValue)

Detailed Description

Shared helpers for the LAPACK wrappers, such as leading_dimension().

Not a solver itself.
