Write a program which has differnt cases

I'm writing a program that should allow a user to pick from a list of 20 different mathematical cases. Once the case has been selected they are allowed to input 6 different variables. After that the program should use the numbers and the case selected and do the computation. How do I start on this? and are there any examples like this?

Hint:

case_names = cellstr( num2str((1:20).', 'case #%d') );

choice = menu('Pick one', case_names{:});

switch choice
   case 1: ....
   otherwise: ....
end

I appreciate it man. Is there anyway to let the user input the 6 values in that GUI itself after the user picks a case?

This is what I'm using now

case_names = cellstr( num2str((1:20).', 'case #%d') );
choice = menu('Pick one', case_names{:});
switch choice
 case 1
     r1=input('Value =');
     r2=input('Value =');
     re1=input('Value =');
     re2=input('Value =');
     rf1=input('Value =');
     rf2=input('Value =');
     disp(addition of everything)
 otherwise
end

The problem is it exits from the pick window and goes into matlab
