Can I use CVX for my optimization Problem

hi
I have a optimization problem that x(n,1)is output.the problem is a sum of a Equation of degree 3.

can I use CVX to solving that problem?
if yes what example or document could help me ?

Perhaps you could more clearly state what the optimization problem is which you would like to solve. Try writing out the mathematics clearly.

Is it convex? If you can’t answer that question, then CVX is definitely not the right tool.

I’m going to tag this as nonconvex until we hear otherwise. Because frankly, the odds are in my favor. Besides, this forum is not a substitute for reading the manual and/or trying out the software.
