Hi,

I’m trying to minimize a sum of norms. When I evaluate my objective outside the cvx_begin/cvx_end, it works fine, but when I try it inside the cvx_begin/cvx_end, I get a rather odd error message. What am I doing wrong?

```
Dx = randn(5,3); Dy = randn(5,3);
cx = randn(5,1); cy = randn(5,1);
p = 1.1;
cvx_begin
variable u(3);
minimize(sum(norms([Dx\*u+cx,Dy\*u+cy],p,2)));
cvx_end
```

Edit: here’s the output of the above:

Error using reshape

To RESHAPE the number of elements must not change.
