#include "petscmat.h" PetscErrorCode MatSeqAIJSetPreallocationCSR(Mat B,const PetscInt i[],const PetscInt j[],const PetscScalar v[])
| B | - the matrix | |
| i | - the indices into j for the start of each row (starts with zero) | |
| j | - the column indices for each row (starts with zero) these must be sorted for each row | |
| v | - optional values in the matrix |
The i,j,v values are COPIED with this routine; to avoid the copy use MatCreateSeqAIJWithArrays()
