accessing SPQR_qmult from C #10

Closed lkapelevich closed 4 years ago

lkapelevich commented 5 years ago

In https://github.com/jluttine/suitesparse/blob/master/SPQR/Source/SuiteSparseQR_qmult.cpp there are functions to apply a Q factor to a dense or sparse matrix. But in this header file: https://github.com/jluttine/suitesparse/blob/003319cab6429a61aed5b311f5957fce28ce06fd/SPQR/Include/SuiteSparseQR_C.h#L196 the description says SuiteSparseQR_C_qmult applies only for the dense case. Is there is no C interface for applying Q to a sparse matrix? Or am I missing something?
