MATLAB: Simulink.Parameter Trouble

simulink

I have the following function
function CheckA2L(Signal)
         %%%%%%Check to see if signal in a2l file
         A = ehooks_get_msmtvariable_properties(Signal);
         if isempty(A) && strcmp(const_value(1),'K')
            Signal = Simulink.Parameter;
            Signal.Value = 1;
            Signal.StorageClass = 'ImportedExtern';
            save('MissingCals','Signal','-append')
         end
What I am trying to do is have a new Simulink.Parameter that has the same name as the input to the function then set some properties and save it to an mfile. The only PArameter being made is Signal because it is on the left of the equal sign. How do I create a Simulink parameter with the name of the function input?

Do you mean that you want to create a Simulink.Parameter object that has the same name as that of the input argument in its caller workspace? In other words, if I invoked your function using CheckA2L(someObj) from the base workspace, you need an object called "someObj" created? If yes, you can use the inputname function as follows:
function CheckA2L(Signal)
  %%%%%%Check to see if signal in a2l file
  A = ehooks_get_msmtvariable_properties(Signal);
  if isempty(A) && strcmp(const_value(1),'K')
    Signal = Simulink.Parameter;
    Signal.Value = 1;
    Signal.StorageClass = 'ImportedExtern';
    eval([inputname(1) '=Signal;']);
    save('MissingCals',inputname(1),'-append')
  end
