From numpy import interp

Webnumpy.interp is defined as like below: numpy.interp(x, xp, fp, left=None, right=None, period=None) Here, x is an array_like x-coordinates to evaluate the interpolated values. xp are the x-coordinates of the data points and fp are the y-coordinates of the data points. The size of both should be equal. WebWhen the ‘interp’ mode is selected (the default), no extension is used. Instead, a degree polyorder polynomial is fit to the last window_length values of the edges, and this polynomial is used to evaluate the last window_length // 2 output values. cvalscalar, optional Value to fill past the edges of the input if mode is ‘constant’. Default is 0.0.
