I have two lists to describe the function y(x): x = [0,1,2,3,4,5] y = [12,14,22,39,58,77] I would like to perform cubic spline interpolation so that given some value u in the domain of x, e.g. ...

I need to use the "not-a-knot" cubic spline for interpolation in my R scripts. Although there are some R packages for splines, none of them seem to consider the "not-a-knot" typ...

I am searching the equivalent Matlab command Vq = interp3(X,Y,Z,V,Xq,Yq,Zq) in Python. In Matlab I can use the method 'spline' interpolation, which I can not find in python for 3D data. There ex...

I'm stuck with interpolation in Swift. Can anyone help me with that? I want to interpolate the float array (say [0, 0, 100, 25, 0, 0, 0, 25, 0, 0, 0]) into another array with some given size (for e...

I'm having difficulties to perform a spline interpolation on the below set: import numpy SOURCE = numpy.array([[1,2,3],[3,4,5], [9,10,11]]) from scipy.interpolate import griddata from scipy.interp...

I have the data as shown below. I want to find a CUBIC SPLINE curve that fits the entire data set (link to sample data). Things I've tried so far: I've gone through scipy's Cubic Spline Functio...

I have a signal which I want to remove the basline drift using the picewise cubic spline algorithm in MATLAB. d=load(file, '-mat'); t=1:length(a); xq1=1:0.01:length(a); p = pchip(t,a,xq1);...

I have the following piece of code. It generates the 3-D cubic spline of the given 3-D function given in parametric form. I pretty much adapted this to my case using the online documentation for sp...

My bold claim is that the Octave implementation of the cubic spline, as implemented in interp1(..., "spline") differs from the "natural cubic spline" algorithm outlined in, e.g., Wolfram's Mathworl...

I'm trying to do something like the following (image extracted from wikipedia) #!/usr/bin/env python from scipy import interpolate import numpy as np import matplotlib.pyplot as plt # sampling ...

So i was writing a python program for my numerical course, and I had to code a cubic spline program. So i implement the formula for cubic spline given in books like Numerical methods by Chapra and ...

I want to perform a (cubic) spline interpolation for population data to "transform" yearly data into quarterly data. I know that there are a fair number of flaws doing so, but I need to d...

I'm trying to calculate a Bezier-like spline curve that passes through a sequence of x-y coordinates. An example would be like the following output from the cscvn function in Matlab (example link):...
