index exceeds matrix dimensions

I would appreciate if anyone could advise as to why I am receiving this error. note, x is a multiple of windowSize.

cheers Christy Burger

clear; clc; close all; 
x = load('RotationSpeed.csv');
windowSize = 10; 
b = (1/windowSize)*ones(1,windowSize);
ii = 1;
yTemp = 0;
for n = windowSize-1: length(x) 
    m = 0;
        for j = 1 : windowSize
            temp = b(j)*x(n-m);
            yTemp = yTemp + temp;
            m = m - 1;
            n = n + 1;
        end
    y(ii,:) = [yTemp];
    ii = ii+1;
    yTemp = 0;
end

Type the following at the command line:

dbstop if error

Then run your code. When the error occurs, the debugger will pause the code at the line of the error with all variables intact. Examine them for dimensions and for the indexing you are using on that line. Then figure out why the dimensions or indexing is not what you expected.

Solved it. Thank you very much for the advice. I won't forget this one!
