There is a special case, named 'pchip' in Matlab. pchip stands for 'piecewise cubic Hermite interpolating polynomial '. The key features of the pchip interpolation in Matlab is that it is shape preserving and“ visually pleasing”. The key idea is to determine the slopes so that the interpol...
MatlabNewton basispolynomial interpolation techniquesspline functionsTo consider algorithms for evaluating polynomials or reformulating them with respect to different bases, this chapter reviews polynomials as tools for solving interpolation problems. The process of solving the interpolation problem is generally ...
Compute interpolations at the query points using spline, pchip, and makima. Plot the interpolated function values at the query points for comparison. Get x = -3:3; y = [-1 -1 -1 0 1 1 1]; xq1 = -3:.01:3; p = pchip(x,y,xq1); s = spline(x,y,xq1); m = makima(x...

MATLAB also has the function spline to perform one-dimensional interpolation by cubic splines, using the not-a-knot method. It can also return coefficients of piecewise polynomials, if required. The functions interp2, interp3, and interpn perform two-, three-, and n-dimensional interpolation, ...
In this project, we provide the source code of polynomial interpolation methods for smooth trajectory interpolation, including the linear interpolation, parabolic interpolation, cubic interpolation and interpolation of polynomial with five degrees. There are two branchs for both Matlab and Python. The exp...
