Solve real affine/ concave

Please guide.
Is there any way to solve a cvx variable (matrix) divided by a concave function. I have read that product of two cvx variable is niether convex nor concave so cvx does not accept it. But what about this? Can inv_pos function be used for this?

You’ll have to be more specific in what function you are trying to model in CVX. What’s in you other post is non-convex.

My function is like XY/log(1+p) where X Y and p are cvx variables matrices. cvx can not solve it directly so i was trying to relax the problem but s
like you said i think not possible. Sir, can you suggest any other software which is easy to use like cvx and can solve it?

You can try YALMIP .
