![]() ![]() If you have multiple sets of data that are sampled at the. Vector xq contains the coordinates of the query points. ![]() Vector x contains the sample points, and v contains the corresponding values, v ( x ). Examples collapse all Interpolation of Coarsely Sampled Sine Function Define the sample points, x, and corresponding sample values, v. Piecewise linear interpolation - MATLAB Cody - MATLAB Central Problem 970. ![]() I had to write it in German unfortunately (was for school) but the matrix might help you anyway. vq interp1 (x,v,xq) returns interpolated values of a 1-D function at specific query points using linear interpolation. pp interp1 (x,v,method,'pp') returns the piecewise polynomial form of v ( x) using the method algorithm. The matrix is filled like shown in that document on page 17. I have written a web tool that performs a cubic inteprolation and my approach was to calculate the coefficients by solving a matrix using the gaussian elimination. Usually the equations look like this (for example with the following set of points): ![]()
