PetscErrorCode MatSeqDenseSetPreallocation(Mat B, PetscScalar data[])

Collective

Input Parameters#

  • B - the matrix

  • data - the array (or NULL)

Note#

The data input variable is intended primarily for Fortran programmers who wish to allocate their own matrix memory space. Most users should need not call this routine.
