I want to call multiple files and plot them using a loop
显示 更早的评论
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
