MatDenseHIPPlaceArray#
Allows one to replace the GPU array in a MATDENSEHIP matrix with an array provided by the user. This is useful to avoid copying an array into a matrix.
Synopsis#
PetscErrorCode MatDenseHIPPlaceArray(Mat mat, const PetscScalar *array)
Not Collective
Input Parameters#
mat - the matrix
array - the array in column major order
Note#
You can return to the original array with a call to MatDenseHIPResetArray(). The user is
responsible for freeing this array; it will not be freed when the matrix is destroyed. The
array must have been allocated with hipMalloc().
