I want to plot cell array M{k} that has vectors of different size. How to do it ?
How to transpose it ?
plot(M{:}) returns error.
M{k}
[1, 2]
[1,3 , 5]
[1,3,5,6,7]
[1]
etc..

How are you envisioning that this data should look like on the plot? I.e., if you weren't getting an error, what would you expect the plot to look like? What points or lines would be there for your representative data above?

• Your file has a cell array which contains different length data in each cell
• if you wants to plot a specific cell data you can use the below code
plot(cell2mat(M1(1,100)))% to plot data in 100th cell

Try this:
M={[1, 2]
[1,3 , 5]
[1,3,5,6,7]
[1]}
for k = 1 : length(M)
M{k}
plot(M{k}, 'b*', 'MarkerSize', 13, 'LineWidth', 2);
hold on;
end
grid on;
xlabel('Index', 'fontSize', 20);
ylabel('Value', 'fontSize', 20);
If you want, you could plot each cell in a different color, like
plot(M{k}, 'b*', 'MarkerSize', 13, 'LineWidth', 2, 'Color', rand(1,3));
