This seems like it should be straight forward, but I’m not seeing much …

I have a 2D array A of complex values, but I need an array of its absolute values (magnitude). I naively write, B = abs(A), but of course, it does not work.

This is simple, right?

Try

```
B = abs.(A)
```

Here the . is used for broadcasting, see Multi-dimensional Arrays · The Julia Language

Edit: see also the simpler Functions · The Julia Language

Does

```
abs.(A)
```

do the trick?
