# cpower

cpower is used to create a conic model of rational powers.

### Syntax

```
y = cpower(x,p);
```

### Example

Plot a TV-screen!

```
x = sdpvar(2,1);
plot(sum(cpower(x,4)) <= 1);
```

### Comment

The operator is implemented using a graph representation based on a second-order cone models, and can thus only be used in scenarios where YALMIP can propagate convexity in a conic form.

In nonconvex scenarios, or when you do not want to generate a conic mode, simply use standard power, **x.^p**.
