I am using matlab to solve bivariate polynomials. Following the example of Matlab, I typed "groebner::gbasis([x^2 - y^2, x^2 + y], LexOrder)", but I received "Error: Unexpected MATLAB operator.". Can anyone help? Thanks.

That is a MuPAD command:

It needs to be entered in a MuPAD notebook, or you can run it in MATLAB by
using one of the commands on this page:

Thanks.

Can you demonstrate how to write the correct code using my example?

Thanks.
