Loading text files by looping through two number sequences

I have 1800 files that I wanna loop through. They're named cut1_1 to cut90_20. The first number goes from 1 to 90 and the second number goes from 1 to 20. I understand that I have to have two loops but loading each file onto solidworks is giving me a hard time.

You do not need two loops. You can use a routine such as https://www.mathworks.com/matlabcentral/fileexchange/10959-sort_nat-natural-order-sort to sort the file names into numeric order.

However, using two loops should be easy enough:

for casenum = 1 : 90
    for subsetnum = 1:20
        filename = sprintf('cut%d_%d', casenum, subsetnum);
        do something with filename
    end
end
