How do I get an array of deviations from 0 or 2 pi radians from an array of bearings ranging 0 to 2 pi?

I have a one dimensional array, basically a row from my 2d array of many rows, of bearing from 0 to 2 pi radians.

I want a new array that shows me how far off from 0 or 2 pi radians each element is.

So I tried

```

mod_arr = mod(arr_of_bearings, (2*pi))

```

but this is obviously wrong.

What would be a correct way to do it.

Most of bearings are near 0 or 2 pi radians so are like 0.0134, 6.2456, etc.

You can calculate the Euclidean distance. Read about pdist. You can calculate difference along x and y axes, read about diff, gradient.
