function C = kronecker (arg1, arg2, arg3, arg4, arg5, arg6, arg7)
%GRB.KRONECKER sparse Kronecker product.
%
% C = GrB.kronecker (op, A, B, desc)
% C = GrB.kronecker (Cin, accum, op, A, B, desc)
% C = GrB.kronecker (Cin, M, op, A, B, desc)
% C = GrB.kronecker (Cin, M, accum, op, A, B, desc)
%
% GrB.kronecker computes the Kronecker product, T=kron(A,B), using the
% given binary operator op, in place of the conventional '*' operator for
% the built-in kron. See also C = kron (A,B), which uses the
% default semiring operators if A and/or B are GrB matrices.
%
% T is then accumulated into C via C<#M,replace> = accum (C,T).
%
% See also kron, GrB/kron.
