How do I make a user defined function with the input being the file name in a string?
显示 更早的评论
I want to make a user defined function where the user can just type in the file name as the input. For example, if my file is called 'graphs.csv' and my function is called power, I want to be able to do
power('graphs.csv') and for the function to run. How do I make this as my input?

Sure, this is easy (do NOT use the name power, as this is already used by MATLAB):
function myfun(filename)
data = csvread(filename);
...
end
and call it like this:
myfun('graphs.csv')

The users will probably very quickly get very tired of having to type in a fully-qualified file name.
I'd suggest something more on the lines of
function [returns?]=power
fn=uigetfile;
if fn==0, return, end
% function does whatever with the returned filename following
...
end
