(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

det(K-lambdaM)=0

K is stiffness and M is mass matrix

2. Relevant equations

How do I make sure that Q'*M*Q=I

Where Q is the matrix whose column entries are the eigen vectors.

3. The attempt at a solution

I want to know how to do it without matlab help. Is it always true that I will get a diagonal matrix?
