Index is out of range when creating 3D arrray

This is a part of program code for reading csv file and creating 3D array.

But when runnig the code , the error "Index is out of range" occurs.

How is this code modified?

Providing supplementary information about this code, NUM_data = 40

list = dir(path); 
list={list.name};
list = natsortfiles(list);
list = string(list);
 
for n = 1:length(NUM_data)
    list(n);
    X(:,:,n) = dlmread(list(n));
end
 
X_three_way = permute(X,[3 2 1]);
sample = X_three_way;

If NUM_data = 40, then your code should sth like this one:

...
for n = 1:NUM_data
    X(:,:,n) = dlmread(list(n));
end
 
...
