MatDenseReplaceArray#
Allows one to replace the array in a dense matrix with an array provided by the user. This is useful to avoid copying an array into a matrix
Synopsis#
#include "petscmat.h"
PetscErrorCode MatDenseReplaceArray(Mat mat, const PetscScalar *array)
Not Collective
Input Parameters#
mat - the matrix
array - the array in column major order
Note#
Adding const to array was an oversight, see notes in VecPlaceArray().
The memory passed in MUST be obtained with PetscMalloc() and CANNOT be
freed by the user. It will be freed when the matrix is destroyed.
