Hello,

How to make bode plot in Smath Studio like below in Mathcad prime?
Only x-axis is in logarithmic

But how can I plot these 2?

Cornel,
The arguments for a plot must be a function or a couple of column vectors.
I your case you can use in your plot the vectors you are calculated and use as input for the graph:

But I want to plot augment(freq, 20*log()) and augment(freq, arg()), which does not work..this îs the problem

augment(freq, arg()) and augment(freq, 20*log()) really works... only must adjust the axis... your yaxis is set 0~100 and your data appear in the 0~(-100) axis

I'm starting to dislike Smath's problems/bug and that is not working continuously fine...2 days ago I could see the Zedgraph settings, and now when I try to enter in the settings of Zedgraph, Smath crashes...

Now I am done with being polite.
If you don't like this much, use another program.

Aren't you annoyed by the fact that SMath doesn't continously work well?

I'm trying to give SMath a try because I like that it has better symbolic calculation capabilities than Mathcad Prime, but I also see SMath's shortcomings or things that are easy to see in Mathcad Prime but not in SMath...

Actually, no I am not. Because SMath works as it is intended.
Near everything you can do with mathcad v15, you can do with smath, in some way.
Just not with exact workflow. You only have to put some effort on SMath.
These two programs are similar but not same.

Base program has some inferiority in some areas, but with plugins it can be quite comprehensive.
I can say what is your problem, you invested so much for other programs.
We use SMath for 10+ years, we know how it works. You don't.
You need to learn smath way, not mathcad way.


In addition, smath symbolic operations are much primitive.
That's why we use maple or maxima plugin for that purpose.

Let's see then how things will evolve in futute. I hope to learn SMath way, but for sure I will need your/this comunity members suport.

Well, this is the good part.
If someone knows it, you will always get your questions answered.
And usually, one of hyper-intelligent member of this forum knows the way.
We have a lot of doctors and professors here.
