It seems I don't have this function. I checked my configuring options, in particular

--with-scalar-type=complex

so I'm sure that a PetscScalar variable is handled as a complex number. I tried to use the PetscRealPart but it says:

error: 'PetscRealPart' was not declared in this scope

I included also the header "petscmat.h" but there isn't defined this function.

It seems that I don't include the right header, I googled it but I didn't find it. Which header shiuld I include?

thanks

Is there a function already avilable to get the real part of a petscscalar value?

PetscRealPart() and PetscImaginaryPart()
