How do I make my program accept inputs from an xbox 360 controller and store the input? Script already wrote.

Hey, so I made this nuclear casuality estimator for my maths uni matlab project. Instead of the user typing in the numbers eg altitude, yield etc, how can I make the xbox (wired) controller axis joysticks be used to put in the input? Eg raise left joystick axis up and it raises the number, then they press the b button and it goes to the next part of the script. Here is an example of some of my code and a video of the program.

Example of my code: ------------------------------------------------------------------------------------------------------------------- altitude = 'Please enter the altitude in metres you wish to detonate: '; altitude = input(altitude); if (altitude<=100); tts('This is an aerial burst estimator, please enter a number greater than 100 metres.'); disp(' ') disp('This is an aerial burst estimator, please enter a number greater than 100 metres.') return end if (altitude>100000); tts('The Test Ban Treaty of 1963 prohibits nuclear weapons tests "or any other nuclear explosion in the atmosphere, in outer space, and under water.'); disp(' ') disp('The Test Ban Treaty of 1963 prohibits nuclear weapons tests "or any other nuclear explosion"') disp('in the atmosphere, in outer space, and under water.') return end

------------------------------------------------------------------------------------------------------------------- So, how can I make it so that the joystick can be used as the input there instead of typing in a number? My intention is to strip the controller apart after and then make a project box so I can figure out haptic feedback to make it more interactive. I messed with vrjoystick, but ive been scratching my head for weeks. I even bought this to make a final throw switch...(once ive stripped the xbox 360 wired controller down).

My program (Has EMP simulation, lol)
