I want to call multiple files and plot them using a loop

Greetings

Lets say I have 'n' number of .mat files with random names, now, I want to call them, use some equations and plot them, but all on the same graph. Can I do that using a loop and make my life easier?

Right now I am calling them sperately like this (this is just for calling 1 file):

dirdata1 = dir('Smooth_cylinder_5ms_3D.mat');

file = dirdata1';

s = load(file.name);

L = extractfield(s,'b')';

a1 = s.b;

U_bar_2_1 = mean(a1)';

U_inf_2_1 = max(U_bar_2_1);

ud_2_1 = max(U_inf_2_1-U_bar_2_1);

yplus_2_1 = (y)/(nu/ud_2_1);

u_prime2_1 = [];

Uplus_2_1 = U_bar_2_1/ud_2_1;

..........

And then I plot using this(this is just for 1 file, it goes on until n number of files): Also I am running out of coloured lines how do I encounter that?

plot(y/D,U_bar_2_1/U_inf_2_1,'k-'...........

hello

attached a few examples - they are for excel / csv files but you can easily change the code for mat files (like : ... = uigetfile('*.mat')

hope it helps

I think I forgot to mention.. those .mat files are double i.e. they are a 491601x39 double files. So each file needs a seperate line plotted. And I want all those lines on the same figure with different colour.
