I have the following coordinates stored in arrays that I want to convert into polar coordinates :
import numpy as np
R = 1.;
NcellB = 5;
xm = np.linspace(-R, R,NcellB);
ym = np.linspace(-R, R,NcellB);
Is there a simple and fast way to do it?

I saw this already, it is defined for a single couple (x, y). I was looking for a better way without having to use two for loops, which costs a bit in calculating time... – ynasroal Oct 22 '20 at 15:25

Both np.sqrt and np.arctan2 accept array as input, so no for loop is required. – cssstudent Mar 06 '23 at 02:54
