Non-Trivial Eigenvector

Hi,

I am trying to solve the eigenvectors of matrix k-lambda*m, similar to [vec, val] = eig(k,m) in matllab.

However, there is no such built in function in Mathcad. I write a similar equation in solve block,

but mathcad tends to return to the trivial solution.

Is there a way to restrain mathcad from producing trivial solutions?

Thank you guys!

Best
