    You missed the "s" in "eigenvals" and so "eigenval" is treated by the symbolics as an unknown/undefined function.

    Unfortunately Prime seems not to be able to calculate the eigenvals of your matrix - I get an "unknown error".

    Sure 😉

    But as the denominator of the elements in your matrix S is the same, you may help yourself by getting rid of it for the calculation of the eigenvalues and add it manually:
