Added sorting of eigs in function 'principal_stresses' #125

Closed ioannaMitropoulou closed 2 years ago

ioannaMitropoulou commented 2 years ago

The numpy linalg.eigs() function does not sort the eigenvectors/eigenvalues by magnitude. I added a small check so that the min/max fields are filled in by the larges/smallest eigenvector+eigenvalue respectively
