Loading and Plotting .mat file

Please view the files below, I need help plotting them. Thanks in advance.

[Dyuman Joshi]

Use load to load the variables from the .mat files into workspace and use the appropriate function to plot the data.

[Abdulla AlAnsari]

Can you help me with the ‘appropriate function’. I can load all the Files in. Just issues with plotting.

"Can you help me with the ‘appropriate function’."

That depends. Which type of plot do you want to do?

I need my plots to be similar to the below:

Well @Abdulla AlAnsari, @Star Strider has been kind enough to provide you with a full working solution.

Check the answer below.

If you want to plot the ‘wl’ field in each one, this works —

Files = dir('*.mat');

figure
tiledlayout(3,3)
for k = 1:numel(Files)
    Name = Files(k).name;
    LD = load(Files(k).name);
    wl = LD.wl;
    nexttile
    plot(wl(:,1), wl(:,2),'-r')
    hold on
    plot(wl(:,1), wl(:,3),'-b')
    hold off
    grid
    grid('minor')
    title(Name)
end

Make appropriate changes to get the desired result.

Added this —

Apparently this is a ‘guess what I want to plot’ problem.

Select the ‘wl’ field instead, since that appears to be the most promising.

Choose the two files you want to plot, using the ‘FileSelection’ vector (any two will work, and in any order, providing the numbers are between 1 and 9).

figure
tiledlayout(2,1)
FileSelection = [7 6];
for k = 1:2
    Name1 = extractBefore(Files(FileSelection(k)).name,'.');
    LD1 = load(Files(FileSelection(k)).name);
    wl1 = LD1.wl;
    % Name2 = extractBefore(Files(k+1).name,'.');
    % LD2 = load(Files(k+1).name);
    % wl2 = LD2.wl;
    nexttile
    plot(wl1(:,1), wl1(:,2), '-r', 'DisplayName','Input Signal')
    hold on
    plot(wl1(:,1), wl1(:,3), '-b', 'DisplayName','Response')
    hold off
    grid
    grid('minor')
    xlabel('Time (s)')
    ylabel('Input Signal (rad/s)')
    legend('Location','best')
    title(Name1)
end
