How do I do this? Pass a filename to a function?
Show older comments
I have created a function to browse a file in a gui. Now I have another function which does some calculations with the variables in the browsed file. So how do I load that file's contents in the new function?

In your first function you pass the filename to the new function:
results = new_function(filename);
Then in new_function you read in the data and do something with it.
function results = new_function(filename)
data = importdata(filename); % of xlsread() or csvread() or readtable() or whatever...
% Now do something with data....

It's whatever variables you want to pass back to the calling routine. You don't have to use it. You can call it whatever you want or even use multiple ones, like
function [result1, result2] = new_function(input1, input2, input3)
Sounds like you need to read the Getting Started stuff about how to write a program and call functions.
