Wondering how to put a function full of switch cases into the app designer so that when a varible is selected in the 'edit feild (numeric)' it does the set equation.
currently this is my function:
function y = UnitConversionsFunction(x, options)
%unit conversions
switch options
case 'c2f'%cel to fah
case 'f2c'%fah to cel
case 'mil2fo'%milliltres to fluid ounce
y= x/29.5735;
case 'fo2mil'%fluid ounce to millilitres
y= x*29.5735;
case 'l2p'%litre to pints
y= x*1.75975;
case 'p2l'%pints to litres
y= x/1.75975;
case 'l2g'%litres to gallons
case 'g2l'%gallons to litres
y= x*4.54609;
case 'kilj2kilc' %kiloj to kiloc
case 'kilc2kilj'%kiloc to kiloj
y= 4.184*x;
case 'pas2psi' %pas to psi
y= x/6894.76;
case 'psi2pas' %psi to pas
y= x*6894.76;
error ('please enter correct option')

This page shows how to add a custom function to an app. Note that the first input is the app structure.
