So I downloaded this script nsumk to do some cool partition of integers for me: https://www.mathworks.com/matlabcentral/fileexchange/28340-nsumk
When i open it in matlab it appears in the editor window, I think it's like in the place where I would normally write scripts (once I get that advanced, haha!). Anyway, what do I have to do from here to get this functiln nsumk running in my command line?? I've tried typing in numk and stuff like that but can't get it to work.
If you can't tell, i'm a total scrub at this stuff, but i'm very interested!!
Simple explanations appreciated!! Peace out!!!!

Please see John's comment as it's important.
Place the function in your current folder and call it from command window, or in write it in script.
[m,x] = nsumk(n,k)

You need to either have defined n and k already as variables, or else pass in particular numeric values.
n = 7; k = 4;
[m, x] = nsumk(n, k);
or
[m, x] = nsumk(7, 4);

I put:
>> n = 7; k = 4;
[m, x] = nsumk(n, k);
into the command prompt and get this:
Error: File: nsumk.m Line: 11 Column: 53
Invalid expression. Check for missing multiplication operator, missing or unbalanced delimiters, or other syntax error. To
construct matrices, use brackets instead of parentheses.
Thx for being patient with me

Weird, I went to that line and put a % at the start of it, now the program runs, Thx
