Thank you!
hello, I'm trying to model a transfer function by specifying the zeros, poles and gain. Following the document that says: TransferFunctionModel[{z,p,g},s] specifies the zeros z, poles p, and gain g of a transfer-function model. I do this...
as suggested by Robit below: Reduce[x * c == y, x] (y == 0 && c == 0) || (c != 0 && x == y/c) that said, I should **always** use `Reduce` rather than `Solve` ???
