Eigen Vector

[SPRstructur]

Dear all,

I re-substitute one of Eigen Value back to Equation (Q^2*M+Q*C+K=0) but get Q=0. 

How can we calculate Eigen Vector (Q) after we know Eigen Value?

Thank you

use the function eigenvec()

[SPRstructur]

function eigenvec() can not use in equation form: Q^2*M+Q*C+K=0 use only vH · M = z · vH
