MatDenseUpdateColumnLayout

Update the column layout of the dense matrix.

Synopsis

#include "petscmat.h" 
PetscErrorCode MatDenseUpdateColumnLayout(Mat A, PetscLayout clayout)

Collective

Input Parameters

• A - the Mat object

• clayout - the PetscLayout object (cannot be NULL)

Notes

Because a dense matrix’s storage is independent of its column layout, this routine can update the layout without modifying the underlying storage.

It can be useful when users want to apply the operator, with MatMult() on a right vector with a different layout.
