WebThe interpolant uses monotonic cubic splines to find the value of new points x and the derivatives there. See scipy.interpolate.PchipInterpolator for details. Parameters: xiarray_like A sorted list of x-coordinates, of length N. yiarray_like A 1-D array of real values. yi ’s length along the interpolation axis must be equal to the length of xi.
