Hello all.

I'm very excited about this release as it is actually the most significant code change for past several years. I've started working on core redesigning (in order to improve performance) on summer 2015 and today results are published! I did my best to provide full back compatibility for plug-ins, but I expect couple of them might be failed to load. If so, please let me know, so I could fix it.

This SMath Studio build passed all internal tests and I believe it is stable enough to start using it today, but just because of too many changes done it will be more safe to check all possible behaviors together before finally releasing it as Stable officially.

Best regards and happy playing with SMath Studio 0.98!

Thank you Andrey, this update is most welcome!

To start off the bug hunt - something does not seem to work for summation:

... And for one reason or another a "attach file" icon is not visible in the forum post menu...

Here is the SMath expression code that does not work:

line 1 :
Code:
y':transpose(mat(-3*'m,3*'m,3*'m,-3*'m,1,4))

line 2 :
Code:
I.x:sum(((el(y',i))^2),i,1,N)


In the cloud: http://smath.info/cloud/sheet/MZvkmGNbq6

Error in the cloud version of SMath is different from the error in the local version

Thank you all! Current nightly build is canceled and will not come as an update anymore. Will do release later this week after all issues is fixed.
For now I suggest you to uninstall 0.98 and install the latest available 0.97.

Sorry for inconvenience!

Best regards.


UPDATE: As we see issues is not actually related to SMath Studio itself, 0.98.5904 is now approved as a Beta again. It will be available via Extensions Manager if it is configured to display Beta-versions of files.

Hi,

The following file worked well in Smath 97.5890 up to yesterday.
But under the latest version, the calculation for definite integral gives an error.
Can somebody help me in this regard please?
Reservoir Flood Capacity Estimation-R1.sm (191kb) downloaded 44 time(s).

It will not work for me as well, although I have to admit that I installed bunch of plugins.



However, fresh install with only Davide's Nonlinear Solvers (FindRoot() function is from there) and Martin's Smath Handbook will give this

1. FindRoot() will give the same error as on the picture
2. Definite integral works

Radovan

Thank you Andrey and to all the developers!
Still hoping for an official portable version ...

Any information on the symbolics? I am trying to recreate a "proof" from a Mathcad file and I'm missing some features (or cannot find). Are we allowed to post Mathcad files on this forum? If so, I will post all of the relevant files.

Please, can you reproduce the error with the file in post #18?

Small delta region can be desabled.

Best Regards,
Ioan

I can reproduce this on the machine with many plugins, but on the machine with almost no additional plugins it was correct.
Therefore, chasing for the problematic plugin should be performed regarding these problems (integration, summation etc).

@Davide
Did you update the Numerical Solvers? I did not find any difference yet regarding FindRoot() problem

Regards,
Radovan

Hi Andrey, apologize for confusion. I have a 30 page SMath file that does not run on 0.98; The error points down to the summation function - I will attempt to replicate it again and post the .sm file here

Try to install a fresh version without any not needed plugin for this file.
I suppose it might work, not sure.

Hi Radovan,

I had a bunch of so many plugins.
So, uninstalled, including all plugins in %APPDATA%/Smath folder and did a clean install.
My problem was solved.

Thank you very much.

Specifically, I thought that "symbolic solve of algebraic equations" was implemented in version .9X. Keywords in symbolics would be fantastic too!
