One of my constraints is :

positive constant value / || A-B||

but CVX don’t let me inverse norm function!!

please help me

The argument of `inv_pos`

must be concave (or affine). Have you proven your problem is convex? You didn’t show constraints, you showed expression assignments; so we don’t know what the actual constraint you want is, and therefore don’t know if the constraint is convex. For instance `1/norm(...) >= 2`

can be rewritten as `2*norm(...) <= 1`

, which CVX will accept if the argument of `norm`

is affine.

Have you shown it is convex? Did you rad the link?

`u(n) indicant of n_th time slot.`
