MatSeqDenseSetLDA

Declare the leading dimension of the user-provided array

Synopsis

#include "petscmat.h" 
PetscErrorCode  MatSeqDenseSetLDA(Mat B,PetscInt lda)

Input parameter

A - the matrix
lda - the leading dimension

Notes

This routine is to be used in conjunction with MatSeqDenseSetPreallocation(); it asserts that the preallocation has a leading dimension (the LDA parameter of Blas and Lapack fame) larger than M, the first dimension of the matrix.

Keywords

dense, matrix, LAPACK, BLAS
