I am trying to split a large piece of code into multiple files in a way that the main file calls the others and makes it work

Try editing your question for readability. It is difficult to parse your sample code.
That being said, in general, you can create a separate file for helper functions that are called by your main function. For example, you could create a function called "changemaze.m" containing:
function changemaze()
set(get(get(gcbo,'Parent'),'Children'),'checked','off')
set(gcbo,'checked','on')
MAZE = zeros(30,40);
switch get(gcbo,'Label')
case 'No maze'
case 'Box'
MAZE([1 30],:) = 1;
MAZE(:,[1 40]) = 1;
case 'Tunnel'
MAZE([1:4 26:30],[1 40]) = 1;
MAZE([1 30],[1:4 36:40]) = 1;
MAZE([10 20],15:25) = 1;
case 'Spiral'
MAZE(1:15,15) = 1;
MAZE(15:30,25) = 1;
MAZE(25,1:15) = 1;
MAZE(5,25:40) = 1;
case 'Blockade'
MAZE([1:10 end-10:end],[1 end]) = 1;
MAZE([1 end],:) = 1;
MAZE([8 22],15:25) = 1;
MAZE(5:10,[10 30]) = 1;
MAZE(20:25,[10 30]) = 1;
case 'Twisted'
MAZE([1 2 3 9 16 31 39 46 61 69 76 91 99 106 121 129 ...

and then call "changemaze" in the main file somewhere...
case 'Mazes' % CHANGE MAZE
changemaze();
feval(mfilename,'Stop')
case 'ShowScore' % SCORE CALCULATOR
...
When you create these separate files, make sure to specify any inputs or outputs that may be required by the main function. From what I can tell, you shouldn't need any inputs/outputs for the example I described because you declare a bunch of global variables (something I generally advise against unless absolutely necessary).
