I want to load files every time for a simulation purpose. I want to change 1 at the end of file name "Data_1500_1" using a loop or any logic that it can load all files by it self. Like I am doing here. Next time i want to load file named as "Data_1500_2" with 2 at the end and then 3,4,5,6... and so on.

if true
A = load('Data_1500_1.mat');
B = load('Data_2000_1.mat');
C = load('Data_3000_1.mat');
D = load('Data_4000_1.mat');
E = load('Data_5000_1.mat');
F = load('Data_6000_1.mat');
G = load('Data_7000_1.mat');
H = load('Data_8000_1.mat');
I = load('Data_9000_1.mat');
J = load('Data_10000_1.mat');
end

Need your guidance.

Why is that a desirable feature? Do you need all of the history of the data saved as different .mat files. Wouldn't it be similar to save a variable to the same .mat file each time which told you which run.

Like, suppose you're outputting data to each matrix. Why not, instead of saving it as a new file, just append this struct:

 data_struct = struct('data',data, 'run_id', run_id)
 save('Data_1500.mat', 'data_struct','-append')

Where run_id is the run you're doing? This would be much simpler and less prone to error. Plus, you wouldn't generate bazillions of little files which is really, really bad for most systems.

Well I have data of each run with same variables but different values inside each of them in all files. That's why i need to load a set of files and plot their data.

Thanks alot jgg...U have given a new idea to append structure. Let me try it.
