Hello,
Can variables in 2.2.3 and/or 3.0 be defined with a certain range (e.g.
real and positive)? If so how?
A place where this commonly is useful is symbolic integration. The
classic example is:
Integrate[Exp[-a x^2], {x, -Infinity, Infinity}] where a>0 and real.
There are many other cases where range definitions are useful. I am
currently doing a lot of symbolic convolution, autocorrelation, and
Fourier transform integration.
Thanks,
