How do I link my key.m nargin function (with switch statements) in my main.m script?

Hi guys, so I'm using MATLAB R2017b and I tried to link my function called key.m and used nargin to switch between the arguments. I want to link this in my main.m file, so that I can run it. The function with nargin looks like this,

    function [cm, percentage]= key(T1,T2,T3)
      if nargin==2 
           switch T1
               case ....
               case ....
         end
           switch T2
                 case ....
                 case ....
           end
    [cm, percentage] = key(T1,T2)

      elseif nargin==3
           switch T1
           case ....
           case ....
           end
              switch T2
                 case ....
                 case ....
              end
                 switch T3
                    case ....
                    case ....
                  end
    [cm, percentage] = key(T1,T2,T3)

I want to link this in my main.m script and run it. Any ideas will be really helpful and highly appreciated. Thank you <3 :)

Just put the following line in your main.m file

[cm, percentage] = key(T1,T2,T3);

As long as key.m is on your Matlab path (so either in your current folder, or in one of the folders that you told Matlab to look for function), you can just use key as you would with any other function.

Just to clarify, you are aware that putting [cm, percentage] = key(T1,T2,T3) in your key.m file will cause a loop?
