using nested loop function to create a matrix

Hi everyone i'm stuck on something that's probably quite simple, wondering if someone can lend a hand

using:

for slowIndex = 1:s

for fastindex = 1:s

H(slowIndex,fastIndex) = movavg(eurUSDClose,'exponential',slowIndex);

end

end

I took this from the MATLAB help section and am trying to amend it for what i need, can some one tell me what I must add to get the loop to run through the fastIndex as well? The end resulty should be a matrix with s number of rows and s number of colums. Eventually fastIndex and slowIndex will contain different values i'm just tryng to get my head around the basics as this stage.

You can watch the 1's being filled in:

s=10;
H=zeros(s);
J=zeros(s);
for k=1:s
    for m=1:s
        H(k,m)=1;%simple double for-loop, first row is filled in, then second row, ...
        J(m,k)=1;%first column is filled in, then second column, ...
    end
end

Thanks for the answer David appreciate it. That did work, probelm is i'm asking the wrong the question, need to have a little rethink about what it is i actully need to get out of this.

Very new with MATLAB!!

Thanks
