Thanks Davide for the WS. "assume" is often needed as well as "real". The most common is "allvalues". It expands the more general RootOf.

I'm still trying to get the hand of this software. I'm an e.e. undergraduate and would like to be able to perform the something like the mathcad at the end of this post. I did try to input a similar syntax but I'm too much of a noob to work it. Can anyone shed some light on this for me? The post shows a trasfer function solved for the poles and zeros... It looks like you have to know how many poles and zeros to solve for before getting going. That would require putting the transfer function in standard form I'm somewhat sure. https://electronics.stac...f-transfer-function?rq=1

You may attack for an export solution.

Jean, Until I get my new pair, I see that a dot appears after the F(s) when I type a comma. Any diagnosis? Inverse Laplace-2.sm (5kb) downloaded 34 time(s).Basile

Any diagnosis? Check from "Options" if you can fix .

After doing my best to incorporate sMath into my University workload for the past 6 months. From my magnetism class to my analog circuits class here at the University of California at Santa Cruz but it has been my experience that for every line of code I write that I generate many more while trying which are unproductive. I think the efforts made on this program are exemplary and I've donated $10 but I think unfortunately I will not be able to continue with it due to the learning curve being so steep. People have done some amazing things with it that I can't even begin to follow but I haven't been as successful. Perhaps as I become more competent I might be more successful but for now I think I will unfortunately have to hang up my hat gentlemen... I bid you a respectful adieu for the time being kind Sirs... hw 2.6.sm (131kb) downloaded 40 time(s). open loop gain from closed loop gain 2.sm (40kb) downloaded 29 time(s). magnetism.zip (5,393kb) downloaded 47 time(s).
