How do I access a MATLAB UI function in another .m file?

Seems like you're doing some sort of combination of two distinct things:

1. Use a simple function, which can be in its own .m file or one of the methods of your main class:

 

% in your initialise class constructor you still have
buttonCreate(app);

% In buttonCreate.m
function buttonCreate(app)           
    % Create file load 1
    app.fileload1 = uibutton(app.gridLayout, 'push');
    app.fileload1.FontSize = 36;
    app.fileload1.Layout.Row = [8 9];
    % ...
end

2. Use a class to hold references to all of your buttons, in which case the objects you create would be properties of that class, rather than the main app object:

 

% in your initialise class constructor you create a buttons
% object and assign it to the buttons property.
% The buttons don't need to know anything about the app, just
% the target grid layout to parent the buttons
app.buttons = buttons( app.gridLayout );

% In buttons.m
classdef buttons < handle
    properties
      fileload1
    end
    methods
        function obj = buttons( grid )           
            % Create file load 1
            obj.fileload1 = uibutton(grid, 'push');
            obj.fileload1.FontSize = 36;
            obj.fileload1.Layout.Row = [8 9];
            % ...
        end
    end
end
