Hello, everybody!

It is well known that \operatorname{trace} (A^{-1}) is convex with respect to A, and there is even a function “trace_inv” in CVX, dealing with this case.

However, right now I need to minimize the function \operatorname{trace} (CA^{-1}C^{\rm T}), having other conditions expressed with respect to A. This target function is also convex with respect to A, but I have no idea, how to implement this fact within CVX.

Is there a way to construct such target function? Which is the best way to do it?

Thanks in advance!
