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...

Syntax isys = interp(sys,freqs) Description isys = interp(sys,freqs)interpolates the frequency response data contained in the FRD modelsysat the frequenciesfreqs.interp, which is an overloaded version of the MATLAB®functioninterp, uses linear interpolation and returns an FRD modelisyscontaining th...
简单来说就是 二维数据插值 下面是matlab给出的解释 INTERP2 2-D interpolation (table lookup).ZI = INTERP2(X,Y,Z,XI,YI) interpolates to find ZI, the values of the underlying 2-D function Z at the points in matrices XI and YI.Matrices X and Y specify the points at which ...

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...
Use the ndgrid function to create a full grid that you can pass to interpn. For example, the following code creates a full grid in R2 for the region, 1 ≤ X1≤ 3, 1≤ X2≤ 4. [X1,X2] = ndgrid(-1:3,(1:4)) X1 = -1 -1 -1 -1 0 0 0 0 1 1 1 1 2 2 2 2 3 ...
there is a bug in MATLAB 7.0 (R14) that affects the way the INTERP2 function handles 4 inputs. To work around this issue, use the following syntax when calling the INTERP2 function:Z = rand(10,10);x = 12; y = 5;[m,n] = size(Z);interp2(1:m,1:n,Z,x,y,'*linear')
Sample grid pointsmatrices | vectors Sample grid points,specified as real matrices or vectors.If X and Y are matrices,then they contain the coordinates of a full grid (in meshgrid format).Use the meshgrid function to create the X and Y matrices together.Both matrices must be the ...
