How to use CVX minimize “trace(X^H X)”, where X is an N*N matrix, and X^H is the conjugate matrix of X.
How to use CVX minimize "trace(X^H X)", where X is an N*N matrix, and X^H is the conjugate matrix of X
Use sum(sum(square_abs(x) ))
Thank you. This method works well.
Another forn, which might be more convenient for certain related problems is:
WoW, received with thanks.
Equivalent to sum(square_abs(x)), but more efficient. Convex.
So you could also do
That’s great! I’ll give it a try.
