Python’s numpy.fmin () computes the element-wise minimum of an array. It compares two arrays and returns a new array containing the minimum values. The difference between the fmin () and minimum () functions in numpy is that the fmin () function ignores NaN values whereas the minimum () function propagates NaN values.
