How to extract a value out of different .mat files and save them into an array

I have to load multiple .mat files, and in those files I want to get the same value out, and then place it into an array

for examle I have 5 files

load('my_file_1.mat');

load('my_file_2.mat');

load('my_file_3.mat');

load('my_file_4.mat');

load('my_file_5.mat');

and in each of this 5 files is the same variable, that hat in each case an other value, and I want those values saved into an arry.

How can I do that, i'm stuck?

Thanks in advance!

[TADA]

s = load('my_file_5.mat');

will return a struct, each variable in the file will be put in a field in that struct

if all files have the same fields, you can put them all in a struct array:

for i = 5:-1:1
    s(i) = load(['my_file_' num2str(i) '.mat');
end

if you are only interested in specific variables from each file you can tell load to only load the variables you need, like that:

s = load('my_file_5.mat', 'X', 'Y'); % if the variables are called X and Y for instance
