Song,
Here is an example.
testlist = {{c, a, b}, {3, 1, 2}};
We want to sort on the first list and have the second list go along with it.
testlist // Transpose // Sort // Transpose
{{a, b, c}, {1, 2, 3}}

Hi everyone,
When i get the eigenvalues and eigenvectors for a matrix. i want to
sort the eigenvalues and hope eigenvectors change the positions
correspondingly. How to do it ?
