Plotting different figures by means of for loop

Hi!

I have a problem with plotting by means of a for loop.

I'll try to explain my case.

I have a 3x4 cell containing mx2 arrays (the two columns represent displacement and load of FE analyses I am performing).

I want to plot load-displacement curves; I want 1 graph per cell row, on each graph 4 curves will be displayed (1 per cell column).

I'll show you how I have tried so far:

for i = 1:cellrows
    figure(i);
    if j < cellcolumns+1
        plot(cell{i,j}(:,1),cell{i,j}(:,2))
        hold on
    else
        hold off
        j = 1;
    end
end 

This is producing the 3 graphs I want, but only 1 curve per graph is displayed (I guess the fourth one, haven't checked exactly). What am I missing?

Hope it's clear, thanks for anyone who's answering.

I believe this does what you are trying to do:

% Create some fake data [Use your real data instead]
m = 5;
C = cell(3,4);
C = cellfun(@(x)[(1:m)' rand(1)*(1:m)'],C,'UniformOutput',false);

% Get the size of the cell array
[cellrows,cellcolumns] = size(C);

for i = 1:cellrows % Loop over the rows
    figure(i); % New figure for each row
    hold on % Make sure each plot does not overwrite the others in this row
    for j = 1:cellcolumns
        plot(C{i,j}(:,1),C{i,j}(:,2))
    end
end

Also, it is strongly recommended to not use cell as a variable name, because it is a MATLAB function.
