Question: Help example of evalm doesn' t work for me


I am trying this evalm example (from the help page of evalm, Maple 12):


alias(Id = `&*`());

# Simplification of matrix operations

evalm((`&*`(`&*`(A, B), 2))*B-`&*`(B, Id));


Error, (in evalm/amperstar) &* is reserved for matrix multiplication

A and B are not defined as Matrix in the help page. Is it the problem?
