// The GrB_assign, GxB_subassign, and GrB_setElement operations all accept
// scalar inputs.  The scalar code is converted to an appropriate GrB_Type
// here.  For user-defined types, the scalar is required to have the same type
// as the matrix being operated on.  This cannot be checked; results are
// undefined if the user passes in a void * pointer to a different user-defined
// type.
