I need to make a function that reads an excel file?

How do I read an Excel file into a function without hard coding it? I want to be able to put the file into the functionhandle with a predefined variable as the xlsx file, but i can't seem to make it work.

Can explain more clearly what you're trying to do. An example of inputs and expected outputs would be useful.

" I want to be able to put the file into the functionhandle with a predefined variable as the xlsx file". Does not make any sense to me. What function handle?

How about this

function [numbers, strings, raw] = MyXlsread(filename)
    numbers = [];
    strings = [];
    raw = [];
    if exist(filename, 'file')
        [numbers, strings, raw] = xlsread(filename);
    else
        message = sprintf('File not found:\n%s', filename);
        uiwait(warndlg(message));
    end
