Method
NumCosmoMathISetget_submatrix_colmajor_cols
Declaration [src]
NcmMatrix*
ncm_iset_get_submatrix_colmajor_cols (
NcmISet* iset,
NcmMatrix* M,
NcmMatrix* M_dup
)
Description [src]
Construct a continuous matrix rectangular $S$ using the columns
from the rectangular matrix M and the indexes in iset. If
M_dup is not null use this matrix to build the submatrix,
otherwise, allocates a new matrix. It writes the columns in $S$
using a colmajor memory scheme. This is useful when using
the output matrix into Lapack routines.
Return value
Type: NcmMatrix
The matrix $S$.
