Hello,

I 'd like to use j as imaginary unit, and I want to display it in the title of a plot using typeset, but it doesn't work (in the expression F):

restart ;interface(imaginaryunit=j);sqrt(-1);
F:=2*sin(w)/w*exp(-j*w*2);F;
plot(abs(eval(F,w=2*Pi*f)),f=0..10,title=typeset('F(j*w)'=F));

Thanks for help in advance.
