In the Maple help to use a matrix defined monomial order it is said to define a matrix and a list of variables and then typing 'matrix'(M,V). But I fail to use it. A very simple example:

M:=<<1,0>|<0,1>>;
V:=[x,y];
Groebner[LeadingMonomial](y^3+x*y, 'matrix'(M, V));

But Maple shows this error:

 

Error, invalid input: Groebner:-LeadingMonomial expects its 2nd argument, tord, to be of type {MonomialOrder, ShortMonomialOrder}, but received matrix(Matrix(2, 2, {(1, 1) = 1, (1, 2) = 0, (2, 1) = 0, (2, 2) = 1}), [x, y])

What is wrong?
