How can i make this code snippet a function?

data1 = load('data1.mat')
data2 = load('data2.mat')
data3 = load('data3.mat')
data4 = load('data4.mat')

full_val = cat(1,data1,data2,data3,data4);

This is where i need the function:

plot(data1.val(1,:));hold on; plot(data2.val(1,:));hold on;plot(data3.val(1,:));hold on;plot(data3.val(1,:));

we can easily how this can become an issue on scale i just want a function to keep drawing the function inside the nx1 matrix full_val across data n

for k = 1:numel(full_val)
    plot(full_val(k).val(1,:))
    hold on
end

You could also use a loop when load-ing the .mat files.

Note that (assuming compatible sizes) you could plot all of the data at once, without a loop:

tmp = cat(3,full_val.val);
plot(squeeze(tmp(1,:,:))
