MATLAB: Do I get this error? Undefined function ‘abs’ for input arguments of type ‘Simulink.Parameter’.

errorsimpowersystemssimulinksimulink.parameter

I get Undefined function 'abs' for input arguments of type 'Simulink.Parameter' error and I do not know why because I do not use any abs functions. I'm useing simpowersystem modeling and i need to have blocks parameters set as ImportedExtrn storage class.

Are you using the parameter as a mask value? There may be something below the mask that is attempting to use the parameter that cannot handle Simulink.Parameter parameters.

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
