Hi,
While trying to solve an optimization problem for a MIMO linear precoder, I have encountered the need to compute the eigenvalues of a matrix [itex]D^{H}A^{H}AD[/itex] where the matrix [itex]A[/itex] is known and the matrix [itex]D[/itex] is a diagonal matrix whose entries contain the variables that need to be optimized (those variables can be assumed to be real without loss of generality).
At first sight, I thought it would be easy but I'm finding myself stuck since any of the ideas I had in mind to do that have been useless.
Any help or idea on how to proceed will be much appreciated.
