int HYPRE_SStructMatrixAddToBoxValues (HYPRE_SStructMatrix matrix, int part, int *ilower, int *iupper, int var, int nentries, int *entries, double *values)

Add to matrix coefficients a box at a time

Documentation

Add to matrix coefficients a box at a time. The data in values is ordered as in HYPRE_SStructMatrixSetBoxValues.

NOTE: Users are required to set values on all processes that own the associated variables. This means that some data will be multiply defined.

NOTE: The entries in this routine must all be of stencil type. Also, they must all represent couplings to the same variable type.

If the matrix is complex, then values consists of pairs of doubles representing the real and imaginary parts of each complex value.
