Sort eigenvectors matrix.

Hello,

I have a block diagonal matrix called G.

I have diagonalized this matrix using eig and obtained the eigenvalues:

And also the eigenvectors:

Is there a way to sort the eigenvectors matrix so that the eigenvectors correspond to their respective block ? And also sort the eigenvalues matrix the same way as the eigenvectors.

Thanks in advance,

RM

Instead of flagging it as unclear, you could also edit your question to clarify it, or post a comment on the answer detailing why that doesn't solve your problem.

Take a look at rsf2csf. For a block-diagonal matrix with 1-by-1 and 2-by-2 blocks, it computes a diagonal eigenvalue matrix and corresponding eigenvector matrix, without rearranging the rows and columns.
