subroutine _qrm_matnrm | ( | type(_qrm_spmat_type), intent(in) | qrm_mat, |
character | ntype, | ||
nrm | |||
) |
This subroutine computes the matrix norm. The return value is a real scalar.
[in] | qrm_mat | the inpur A matrix |
[in] | ntype | the norm type. It can be one of these 1 : 1-norm i : inf-norm f : Frobenius-norm |
[out] | nrm | the output norm |
