What is the difference between relative tolerance (rtol) and absolute tolerance (atol) in allclose().
Somebody please explain the meaning of the following:
np.allclose(center_var,center_a,rtol=1e-02, atol=1e-03)
They are used differently in the formula as you can read here:
If the following equation is element-wise True, then allclose returns True.
absolute(a - b) <= (atol + rtol * absolute(b))
The above equation is not symmetric in a and b, so that allclose(a, b) might be different from allclose(b, a) in some rare cases.
