How to express this kind of constraint (cube over linear) in cvx?

[Mark_L_Stone]

In a similar manner, x^3/y^2 for x,y >= 0 can be modeled per @Michal_Adamaszek’s formulation How can I write this kind of constraint (cube over square) in cvx

Another place to find quad_over_lin, and many other CVX functions, is the CVX Users’ Guide.

New functions for CVX

Reference guide — CVX Users' Guide

and

Overloading for CVX of existing MATLAB functions

Reference guide — CVX Users' Guide

I recommend you read it in order to get maximum benefit from CVX (we are all optimizers here, are we not?). Along with reading and searching this forum.

Note: I edited the thread title to make it easier to search for. I also edited the title of the thread containing @Michal_Adamaszek’s solution to include “cube over square”.
