This calculator allows you to enter any square matrix from 2x2, 3x3, 4x4 all the way up to 9x9 size. It will find the eigenvalues of that matrix, and also outputs the corresponding eigenvectors.For background on these concepts, see 7. Eigenvalues and Eigenvectors ...
How does matlab normalize its eigenvectors?Seems like a case of differing by a unitary transformation between the eigenvectors from MATLAB ans nastran. I would only say you can apply a Gram-Schmidt orthonormalization procedure to both sets and compare them. This should give you a similar (same?)...
My application is the common one of multimodal vibration: set up a mass M and stiffness K matrix using convenient generalised coordinates, then get the eigenvalues and eigenvectors of K*M^-1. This works fine normally, but it gives me wrong eigenvectors when used on the standard example of a...
