Question: How do I solve for the eigenvalues of 16x16 matrix with imaginary numbers when the matrix contains a variable.

I'm attempting to calculate eigenvalues of a 16 x 16 matrix ( which contains a single variable "x".

However, this matrix contains 24 instances of imaginary numbers.

When I try to solve for any number other than x = 0, I get: "Error, (in LinearAlgebra:-Eigenvalues) expecting either Matrices of rationals, rational functions, radical functions, algebraic numbers, or algebraic functions, or Matrices of complex(numeric) values"

Eventually I want to be able to solve for multiple values of x simultaneously.

I'm still fairly new to maple, so I may have overlooked something.
