I have a variable defined as A(100\times 5) which is complex

```
variable A(100,5) complex
```

Then I define as expression as

```
expressions B(5,1) nonegative
B=[norm(A(:,1)) norm(A(:,2)) norm(A(:,3)) norm(A(:,4)) norm(A(:,5))];
```

Now my objective is to minimize the L0 norm of vector B, i.e., minimize the number of non-zero elements in vector B

\min ||B||_0

Can it be done in CVX?
