How to read everything in file and make each a subplot

I have like 10 files (.mat) in a folder that all need to be read

and i wrote the code for the plotting

but i want to make it plot graphs for all the 10 files and make subplots and show up as one

i think i should do a loop but not sure how to make the subplots

Reading your files in a loop depends on what is in them and how you have named them. Without more information, it is not possible to write that code.

One approach to the plots:

x = 0:19;                                           % Create Data
y = randi(9, 10, 20);                               % Simulate ‘.mat’ File Inputs

for k1 = 1:size(y,1)
    subplot(5, 2, k1)                               % Create 5-Row x 2-Column Array Of Subplots
    plot(x, y(k1,:))
    grid
    title(sprintf('Subplot #%d', k1))
end

This will probably work:

cmPer=5.7/362;
secPer=1/30;    
t=secPer*[1:360*30];  

for k1 = 1:size(y,1)
    subplot(5, 2, k1)                               % Create 5-Row x 2-Column Array Of Subplots
    v=cmPer*data.speed;
    plot(t, v)
    grid
    title(sprintf('Subplot #%d', k1))
end

I have no idea what ‘data.speed’ is or what it contains. Consider referring to it as:

v=cmPer*data(k1).speed;

if you have read all your data from all your files into your ‘data’ structure. I still have no idea how you are doing that.
