MatProductClear#

Clears from the matrix any internal data structures related to the computation of the values of the matrix from matrix-matrix product operations

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatProductClear(Mat mat)

Collective

mat - the matrix whose values are to be computed via a matrix-matrix product operation

-mat_product_clear - Clear intermediate data structures after MatProductNumeric() has been called

This function should be called to remove any intermediate data used to compute the matrix to free up memory.

After having called this function, matrix-matrix product operations can no longer be used on mat

This frees the Mat_Product context that was attached to the matrix during MatProductCreate() or MatProductCreateWithMat()
