Eigenvalues and Eigenvectors , EGV function .
2009-07-16 by mspokkio
Hello , I have a question regarding EGV function . I've to calculate EGV (values and vectors )of a matrix like : [K]-a[M] and not [K]-a[I] where I is the identity matrix , M is a diagonal matrix different from the identity one ( mass matrix ), a is the general eigenvalue ( usually called Lambda ) , K is a rigidity matrix . If I calculate EGV(K) I can only have the eigen values/vectors of K-a[I] . Is there a way to calculate automatically eigenvalues/vectors of [K]-a[M] ? Thanks
