Reducing a vector size when it is being updated in a loop

Hi,

I have a vector A that is being updated in a loop, A contains data from a Trial, and the length of it changes with each iteration. I want to make the length of each A the same so the plots are of the same size.

Trial 1 length = 497 x 12, Trial 2 length = 700 x 12 ... Trial 5 length = 687x12 ( I want to get a 497x12 vector for all trials)

I currently have this piece of code, which find the smallest length of the A - the problem is the line of code that the smallest length out is inside the loop and after each iteration it changes.

The smallest number is a hint to how long the array A should be, since it varies for each trial uploaded.

I hope the below code helps

smallest = 10000;
for h=1:5
    
    %code to load all script files
       
    if h==1
        A = dlmread("Trial 1");
    elseif h==2
        A = dlmread("Trial 2");
    elseif h==3
        A = dlmread("Trial 3");
    elseif h==4
        A= dlmread("Trial 4");
    elseif h==5
        A= dlmread("Trial 5");
    end
    
     [x , y] = size(A);
    if x<smallest
        smallest = x; %the smallest length of rows for A
    end
    
    
    
    
    ...
        
end

for h=5:-1:1
    
    %code to load all script files
       
    if h==1
        A = dlmread("Trial 1");
    elseif h==2
        A = dlmread("Trial 2");
    elseif h==3
        A = dlmread("Trial 3");
    elseif h==4
        A= dlmread("Trial 4");
    elseif h==5
        A= dlmread("Trial 5");
    end
    
    Acell{h}=A;
end

smallest = min(  cellfun(@(c) size(c,1), Acell) );

Ashort=cellfun(@(c)c(1:smallest,:) , Acell,'uni',0);


for i=1:numel(Ashort)
    
    figure(i); plot(Ashort{i});
    
end

Thanks for your answer, quite new to MATLAB - what does Acell{h}=A do

Also, when I incoporated to my code, it gave an error

Undefined function or variable 'Acell'.

Error (line 26)

xsmallest= min( cellfun(@(c) size(c,1), Acell) );

what does Acell{h}=A do

It stores A in Acell{h}.

Undefined function or variable 'Acell'.

Shouldn't happen. Did you copy/paste my code? In any case try re-pasting.

Thanks the code works well, inorder to extrapolate the data from the cell so I can use them in my calculations should I use the function celltomat?

No, just grab whichever data set you need by indexing, as in Acell{i}.
