Problem in applying loop

dear

I want to apply loop in a way that there is a window of 2000 samples and will increment by 500 samples...

means window size (w) increase like: 0-2000, 2500-4500, 5000-7000, 7500-9500....till 30000.

then the window (w) apply in same way on data (x) like = 0-2000, 2500-4000 etc...

how can i do this?

x = dath001 % data, size 30000x4

w = hann(2000); % window

datawindow = w.*x(1:2000,:); % apply window in data

You have the Signal Processing Toolbox, so see if the buffer function will do what you want.

ill look into buffer function.

dear

clear all,close all, clc

load ('dath001.mat');

x = dath001; % 30000x4 size

w = hann(2000);

datawindow1 = w.*buffer(x(:,1),2000,-500);

datawindow2 = w.*buffer(x(:,2),2000,-500);

datawindow3 = w.*buffer(x(:,3),2000,-500);

datawindow4 = w.*buffer(x(:,4),2000,-500);

above program give

datwindow1 = 2000x12

datwindow2 = 2000x12

.

.

datwindow4 = 2000x12

I want one variable

datawindow give 24000x4 values.

also tell how i apply loop for datawindow1-4...

Thank you

You do not need a loop. Just create column vectors from the individual ‘datawindow’ results, and concatenate them horizontally.

This will probably work:

datawindow = [datawindow1(:), datawindow2(:), datawindow3(:), datawindow4(:)];

I do not have your data, so I cannot test it with them.

Thanks alot dear....
