Is there a way to do the same using plain MATLAB (without MuPad). I guess MuPad uses symbolic algorithms to calculate the minimum polynomial - is there a function to do the same numerically? If not, is there a way to invoke linalg::minpoly from the workspace. By the way, to the best of my knowledge, the symbolic toolbox doesn't have support for minimal polynomials.
