    Graduate Eigenvalues of AX - XA: Finding Eigenvectors for a Real 2x2 Symmetric Matrix

    Hi all, Here is this problem that I have been at for some time now: find eigenvalues and corresponding eigenvectors of the following linear mapping on a vector space of real 2 by 2 matrices: L(X) = AX - XA, where A is 2 by 2 symmetric matrix that is not a scalar multiple of identity...
