sym/ztrans references non-implemented function #1122

Closed cbm755 closed 2 years ago

For 3.0.0, we could either comment out the @seealso line.

Of course it should be added back if iztrans is added.

@alexvong243f shall we just comment out the @seealso for 3.0.0?

Yes, I think we can add iztrans later.

I (mostly) have an implementation of iztrans, but I'm not sure if I handle the case where it's not possible to find the inverse transform correctly. Currently, it returns an unevaluated limit of an unevaluated integral (using the definition of course, but there're multiple ways to rewrite the definition into something sympy can represent...) when the inverse transform cannot be found.
