// gbassign is an interface to GrB_Matrix_assign and GrB_Matrix_assign_[TYPE],
// computing the GraphBLAS expression:

//      C<#M,replace>(I,J) = accum (C(I,J), A) or accum(C(I,J), A')

// where A can be a matrix or a scalar.

// Usage:

//      C = gbassign (Cin, M, accum, A, I, J, desc)

// Cin and A required.  See GrB.m for more details.

#include "gb_interface.h"

#define USAGE "usage: C = GrB.assign (Cin, M, accum, A, I, J, desc"
