Why do I get this error? Undefined function 'abs' for input arguments of type 'Simulink.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.

I am not using any masks. I just use standard simpowersystem blocks and lookuptables and constants from simulink library.

[Niklas Nylén]

Simpowersystem models are likely masked systems (I don't have it so I can't check). If you use the Simulink.Parameter in the mask of a simpowersystem block there could be a (bad) implementation of abs(parameter) inside that block.
