Really basic question, I have just started using MatLab. I have a function that pulls specific columns out of arrays that could be in any of four data files I am working with. Thus, my goal is to input a filename, have the function load the file, and then return the specific columns. Here is my current function:
function [tlat, trate] = lss_rr(filename)
G = load(filename)
m = G(:,3)
t = G(:,4)
But when I input a filename, the name returns as an undefined variable.

[TL, TR] = lss_rr('YourFile.txt');
Change YourFile.txt to the name of your file.
Do not try to use [TL, TR] = lss_rr(YourFile.txt); as that will try to evaluate YourFile as a variable.
