Finding Eigen values from symbolics

Hi,

I want to obtain eigenvalues symbolic equation for the matrix. Any help would be greatly appreciated.

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:
