Syntax : np.ifft(Array) Return : Return a series of inverse fourier transformation. Example #1 : In this example we can see that by using np.ifft() method, we are able to get the series of inverse fourier transformation by using this method.

This function compare two arrays and returns a new array containing the element-wise minima. If one of the elements being compared is a NaN, then the non-nan element is returned. If both elements are NaNs then the first 2 min read Like
