Hello,
Is there a built in function for extracting eigenvalues and eigenvectors from matrices?
Thanks

Hi. Try this plugin
https://en.smath.com/forum/yaf_postst1918_DotNumerics.aspx
There you have dn_LinAlgEigenvalues and other for Eigenvectors
Best regards

This is my attempt for do eigenvectors without plugins. Sometimes give better values than dot numerics, and other times fails, because I haven't a simple code for do the pseudo inverse for this code, and use SMath's inverse() which have some bugs.
