哈哈。MATLAB 2009b的interp文件 function [odata,b] = interp(idata,r,l,cutoff)INTERP Resample data at a higher rate using lowpass interpolation.Y = INTERP(X,R) resamples the sequence in vector X at R times the original sample rate. The resulting resampled vector Y is R times...

x=[1,2,3];是这样的：插值分内插和外插。如果要求xx对应的yy的值，若此xx在你的x范围内，应当算是内插。比如2.9就是在x=[1,2,3]内，它应当是内插。内插matlab有好多种方法。以下几个都可以。z=interp1(x,y,2.9,'nearest')z=interp1(x,y,2.9,'linear')z=interp1(x,y,2.9...
I have a dynamic model as a MATLAB script that uses griddata function for interpolation. When I tried to implement the same model in Simulink, the only way I could use griddata was by using Matlab Function Block with coder.extrinsic('griddata') command inside. After that the Simulink mode...
Use the meshgrid function to create the X and Y matrices together. Both matrices must be the same size. If X and Y are vectors, then they are treated as grid vectors. The values in both vectors must be strictly monotonic, either increasing or decreasing. Example: [X,Y] = meshgrid(1:...
