SMath Studio

Tiny, but powerful mathematical program with WYSIWYG editor and complete units of measurements support.

Offre numerose funzionalità di calcolo e un'interfaccia utente ricca, tradotta in circa 40 lingue diverse. L'applicazione include inoltre un prontuario matematico integrato.

L'applicazione può essere facilmente estesa in base alle proprie esigenze. Lo strumento integrato "Gestione estensioni" consente di accedere a centinaia di risorse, sia ufficiali che di terze parti, tra cui: esempi d'uso, plug-in, applicazioni basate su SMath Viewer, frammenti di codice, traduzioni dell'interfaccia, libri interattivi, manuali e tutorial.

Thank you Andrey.
I have a few questions

1. Can a snippet be nested? I have a function "snippet" that relies on another snippet. This file is an example and I want to reference only this snippet function which will embed the other snippet function
   
2. Do Snippets need to be saved as SM? I had an issue with my SMZ files which I default to saving everything out of habit. I have not tried this version
   
3. Equation wrap does not work on exponents. I know this feature is a work in progress. I even posted a work around

Sorry for answering a personalized question.
Doctored AFAIU.

Andrey,
User error on the Snippet. Because snippets are static, you can embed one Snippet that calls on another Snippet. I thought it was more of a reference like rfile. I like to go back and update documentation/clarifications as time goes by.

Jean,
The sheet I posted is the second half "liquid" equation, per ASHRAE, to calculate the water vapor pressure. It's parabolic and the numbers are within calculation error due to the coefficients being converted from SI to IP. Disclaimer is in the 2017 ASHRAE Handbook. The sample values that I ran, I was within 0.002 psi of most values published in the handbook ... well within engineering tolerances

What's that second half liquid equation ?, I must have missed something in so many years.
My point [previous reply] was to use Sigma instead of Gyzma.

Has this been figured out or do I need to add it to the wish list?
Postfix operator (dB scale in my case)
I was trying to transcribe some old MathCAD sound calculations

I've missed this thread. Please add it to https://smath.info/bts/ - it is easier for me to manage requests there.

FYI, There appears to be a bug in the forum software as I could not post a hyperlink to the forum page. The URL pop-up came up and it would then lock up my web browser (IE and Firefox). Clicking OK or Cancel did nothing

Unfortunatly 0_99_6670 has an issue to start for me on linux, something about the printer seems to be required.
Hopefully you can make some of this terminal message i get and fix it eventually.

Do you have any printer installed? Can you try to install a virtual one (if it is possible on Linux)?

Hi,

I have problem with new version (6670).


Assigning a variable value with the appropriate unit before the "for" loop causes an error, where the older version (6622) worked correctly.

This is by design. In the example you are trying to set element of scalar by index. This is an error. In previous versions of SMath Studio program just lost value of the scalar, which was wrong.

You have three options here:
1) Remove σ:=100*MPa line at all (actually it gave nothing to you in previous versions of SMath Studio as well);
1) Add Clear(σ)=... before the for loop;
2) Use another name for σ variable.

Best regards.

Best regards.

The change was introduced because issuing an error message was preferred over the danger of silently doing unintended things (SS 3525)

The real problem is in the useless error message "cannot calculate". It is misleading, as not the calculation does fail but the assignment by index to an existing scalar.

A message like "element assignment is only possible for empty or matrix objects" would help. I am not aware of other situations where such an assignment might fail, thus this message could be used by default in failing element assignments.

Topic updated with corrected build 6671. Fixed critical issue for environment without default printer installed and/or OS version less then Windows 7. SMath Studio in the Cloud updated and restored.

Sorry for inconvenience!
Best regards, Andrey Ivashov.

In regards to the previous error, i've tried installing cups with a pdf but haven't completed it yet.

anyway 6671 gives an even larger exception notification

=========================
"element assignment is only possible for empty or matrix objects" ... I like it
"can not calculate" is much more real because there is nothing to calculate.
If some wish list would ask for Mathematica style zillions error messages,
that will not replace reading the Smath Handbook.
"for loop can not index a constant"
"not a scalar assignment" [typical Mathcad style]
As it looks, the matter was to replicate a value.

Andrey,
Last plugin issue was fixed with this AppVersion 0.99.6671. I am now wondering if this caused an issue with the X-Y plugin. I posted a bug report there, but wanted to bring this to your attention
