Hello. I need to solve this problem. I do not know how to describe (in cvx) constraints represented in 5, 6, 9, 10 lines. Specifically I have function E, which depends on complex variables W and angular values theta and phi, for all theta and phi, such that a < phi < b and c < theta < d, E<sigma must be fulfilled.
There is one more question. How to solve this problem, if the function E will include trigonometric (sin, cos) functions? When I tried to work with them earlier in CVX, I got an error.
