I have a cell array which contains nx2 matricies in each cell. I'm trying to figure out how to plot each of those cells (x vs y) in a loop. Any ideas?

This is what I have:

numColmns = size(Data, 2);
for i = 1:2:numCols-1
    A{i} = Data(:, i:i+1); 
end
B = A(:, 1:2:end); %removes empty cells in cell array A
numPlots = length(B); %number of plots to make
tiledlayout(numPlots,1) %total number of plots in a row by 1 column

%insert loop where it automatically plots all cells in B

B gives me B{1}, B{2}, ... , B{n}, etc.

So "A" is your cell array, but what is Data? Give an example of Data, either in a .mat file or with code to generate it.

And what is tiledlayout()? Is that a function you're supposed to build that uses plot()? How many plots do you want? Each curve in a separate plot (using the subplot() function), or all curves on the same plot?

Note A{2}, A{4},... are empty

Hi Khiana,

You can use the below code

A_new ={}; % Cell array declared as A in your code
numColmns = size(A, 2); 
for i = 1:2:numColmns-1
    A_new{i} = A(:, i:i+1); 
end
B =  A_new(:, 1:2:end); %removes empty cells in cell array A
numPlots = length(B); %number of plots to make
tiledlayout(numPlots,1) %total number of plots in a row by 1 column
for i = 1: numPlots
    a = B{i}';
    nexttile
    plot(a(1,:),a(2,:))
end
