Hi

 

Thanks for all the helps. Not use to vectorize a function yet but will do it from now on

Either delete the equal sign at the end or delete the "(s)" after T

 

You have to decide if you want define a function T() (no "=" at the end!) or if you want to define a variable T

This is an old mistake, or rather a flaw.
Once upon a time, the developers of Mathcad created the tandem-operator ... := ... = ..., but forgot to attach it not only to variables, but also to functions. And the error messege is not correct.

HI

 

Thanks a lot for all your helps. I deleted the "=" at the T(s) expression and it is now working. Unfortunately I have one more question, may not related to the original question.

 

I defined D(s):=|T(s)| and vectorized on top of the |T(s)|, then I evaluated the D(s) expression and it seems correct.

 

However, when I try: MAG_T(s):=[(Re(T(s))^2+(Im(T(s))^2]^0.5 returns values around 10^-54 which is a very low number and its results do not match with D(s):=|T(s)| vectorized which returns around 0.06 or so

Do you know why?

 

Please see attached file

 

Thanks for your helps again
