Hi everyone I have the folllowing code which gives me a cell array y{m,ind} and i would like to plot in the same figure

y{1,1}, y{1,2}, y{1,3}up to y{1,5} but i cant figure out how to do it.

Preferably i would like to be able to do this for multiple values of m at the same time(i.e. m=1, m=3, ..).

So to have lets say 3 figures for m=1, m=3 and m=5 and in each on of these figures to have the 5 y{m,ind} plots.

I hope i explained it clearly

outLoop = [2,4,8];
outLoop1 = [1, 3, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100];
for r = 1 : numel(outLoop)
    r = outLoop(r); 
    
    for m = 1 : numel(outLoop1)
    m = outLoop1(m); 
    
    for ind=1:5 
        y{m,ind} = mean(vertcat(y{:,r,m,ind}),1);
        
    end
    end
end

What is this

outLoop = al;

The variable is not defined. You can use arrays why use cell array? To plot just use plot.

Thank you for your answer KSSV.

al= [2,4,8]

but eitherway this is part of a bigger code which i can't upload since i can't upload the corresponding images it analyses.

Thank you for your answer i do know about the command plot but i can't use it correctly for cell array.

hello

maybe this ?

I replaced the " mean(vertcat(y{:,r,m,ind}),1) " by a simple random number

clc
clearvars
outLoop = [2,4,8];
outLoop1 = [1, 3, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100];
al= [2,4,8]
for cr = 1 : numel(outLoop)
    r = outLoop(cr); 
    
    for cm = 1 : numel(outLoop1)
    m = outLoop1(cm); 
    
    for ind=1:5 
        %y{m,ind} = mean(vertcat(y{:,r,m,ind}),1);
        y{m,ind} = rand(1,1);
        
    end
    figure(cm)
    plot([y{m,:}])
    
    end
end
