// gbsubassign is an interface to GxB_Matrix_subassign and
// GxB_Matrix_assign_[TYPE], computing the GraphBLAS expression:

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

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

// Usage:

//      C = gbsubassign (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.subassign (Cin, M, accum, A, I, J, desc)"
