VecReplaceArray#

Allows one to replace the array in a vector with an array provided by the user. This is useful to avoid copying an array into a vector.

Synopsis#

#include "petscvec.h"   
PetscErrorCode VecReplaceArray(Vec vec, const PetscScalar array[])

Logically Collective; No Fortran Support

Input Parameters#

  • vec - the vector

  • array - the array

Notes#

This permanently replaces the array and frees the memory associated with the old array. Use VecPlaceArray() to temporarily replace the array.

The memory passed in MUST be obtained with PetscMalloc() and CANNOT be freed by the user. It will be freed when the vector is destroyed.
