Hello. I'm trying to find out the real part of the following symbolic expression:
y0*(y2+jy0)/(y0+jy2)
by using MuPad
I write the following code in the mupad command window
Re(y0*(y2+I*y0)/(y0+I*y2))
but I don't get the result I expect. Do you know how to fix out the issue?

Re(y0*(y2+I*y0)/(y0+I*y2)) assuming ([y0,y2],Type::Real)
or
assume([y0,y2],Type::Real);
Re(y0*(y2+I*y0)/(y0+I*y2));
