Here is a link to the question:Denote by A the 3x3 matrix which rotates by 90 degrees around the z-axis and stretches by a factor of 3 a long the z-axis. Find all eigen values and eigenspaces corresponding to the real eigenvalues.

Would it look something like this..?

0 -3 0

1 0 0

0 0 1

I believes I can the eigenvalues and eigenspaces but I just want to check if my matrix is correct first.

I have posted a link there to this topic so the OP can find my response.
