Dear all ;

I tried to diagonalized a matrix via Lapack .
I can find correct eigenvalue, but the result of eigenvector
isn't correct.
Is there anyone can help me?

<--CUT-->

What makes you think that the eigenvector is not correct? What did you get, and what did you expect as "correct"?

If x is an eigenvector of A, so is c.x, where c is a scalar. Prove it to yourself.

Also the simple case of all eigenvalues being equal is not at all simple.
Much better to try the case of all eigenvalues having differing values.
