Basic MATLAB questions
1.If I am given a transfer function in factorized form e.g (s+1)(s+2)/(s+2j)(s-2j)(s+3) then by which command or set of commands can I get it converted into the polynomial form like A(s)/B(s) ?
2. How can I find characteristic equation of the above example? Like its a polynomial fraction so how do I handle it ?
This is not a question about matlab, but about the symbolic toolbox which is a fronm end to the Maple engine.

And where do I go from there ? I thought tha like 'roots' gives roots of the polynomial so something like that could be done in inverse...please explain...
Actually I am new to MATLAB and I want to know te exact steps in finding a characteristic equation...
