Problem while using fft funtion in the analyticClass #101
Description
The fft funtion from the analyticClass of PSL has a fundamental issue that leads to type error
def fft(self, ya, si):
ns = len(ya)
if ns % 2 == 1: # odd values of np give exceptions
ns -= 1 # make it even
ya = ya[:-1]
v = np.array(ya)
tr = abs(np.fft.fft(v)) / ns
frq = np.fft.fftfreq(ns, si)
x = frq.reshape(2, ns / 2)
y = tr.reshape(2, ns / 2)
return x[0], y[0]The 3rd last and 2nd last line of the code should be
x = frq.reshape(2, ns // 2)
y = tr.reshape(2, ns // 2)
