Hi all,

There is a inverse tangent function in my constraint. Actually, I use the Matlab built-in function “atan”. The expression of this constraint is:

x - atan(y) <= 0,

where x and y are scalar variable, and y>=0.

However, an error appears: **Undefined function ‘atan’ for input arguments of type ‘cvx’.**

Does this mean function “atan” is not supported in CVX？

Thx!
