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.

• [SS-93]: Multiple decimal symbols allowed in variable name now;

Could you please allow both "." and "," to be used and shown as-is in second and following cases in names?

First one, of course, should continue to be converted to "." regardless of which character was used, because otherwise that invisible character (used to create "subscript") may create two different variables that look identically.

But subsequent colons and dots are visible, and thus may be used as is, to avoid different name display depending on current decimal separator, and to enable using intended character (like in Xa,b - here a and b used as list; Xmin.h - here dot is used as separator, and colon would look worse).

Please help -- once it is gone - by itself

All three symbols (., should be allowed, as principle; there are some problems though:
- front-end: triggers arguments separators, if the argument separator symbol is allowed as separator in the subscript;
- back-end: drive properly the plain text;
- back-end: localization conversion (I mean, a.b,c with standard settings should be converted to a,b;c when decimal symbol is set to comma and semicolon is used as argument separator);

2nd and 3rd point can be driven using alternative characters that looks like the others ("greek question mark" ; [U+037E] / "single low-9 quotation mark" ‚ [U+201A] / "small full stop"﹒[U+FE52]

for the first point I guess the only way is to use some shortcut key.

Please help

o_o
Can you share some info about your system? (Operative System, DPI); it appears always or only in some case (new worksheets, existing worksheets)? a clean install might help?

There is a new bug in the interactive handbook. If you follow a link, then the contents of the new sheet is shifted to the position of the mouse click, as if was pasted at that location.

Yes, I'm working on it.
Thank you!

It seems that "i" still causes some headaches. I used a part of one of my standard files and get this rather strange error message



See please the attached file. I have no idea why the famous "i" variable made a mess here

It does not make mess 5346.
FindRoots [Φ.o] looks under defined wrt Maxima that needs a function
whereas it is not a "root". A "root" crosses the X axis. Φ.o can be
anything in the Catesian plane. You can solve point by point but
NOT on a range. Mathcad 11 would not do either. You are in fact,
in other words, "inversing a function". The Mathcad way is the
"seeded root scanner" over a prescribed discrete range ...
as fast as a lighting strike !!!

... neither roots(2) and roots(3) work same as in Mathcad 11 and earlier.
The attached is the Smath 5346 "iterative root scanner". It works but
can't be made "seeded". It re-solves from the starting point. Thus
takes several seconds instead of ~ 0 second if it would keep solving
from the last calculated value [seeded to last value].

I bet there is a twist, but just RemToDo.

In some way, I abandoned because of solving the "data set companion"
not possible in Smath whereas it does not have the Mathcad Given/Find
equivalent.

Thank you Jean for your analysis, but I think that here is again introduced some glitch regarding variable i and for loops. I can not figure out what actually happen here, but I could see that there is something that causes that strange error message. Somehow, in the summation instead of variable "i", you get the actual value of i (I do not know why) and it complains because variable can not start with number.

Radovan

It is not about i, there is a bug in preprocessing wrt the iterator argument of sum() when unknowns are involved in other arguments on definitions; the iterator name is replaced with a value, then when sum tries to evaluate the name is lost.

Thank you Davide

I was quite close to figure this out, but failed. Fortunately, it is not about "i".

Wish you all the best,
Radovan

Must be not define the variable k, which must be defined is the variable x, because apparently, the sum function does not accept symbolic evaluation

Best Regards

Smath 5346 does not suffer the bug that Davide has isolated.

Attached is your project as far as I understand.
Takes 5 min to compute all 35 "Sol" . Works well.
RemToDo: the seeded "solve", I have an idea ?

Андрей, я тут "набросал" черновую версию сборки пакета SMath Studio для Ubuntu 16.04. Будет время - займись. Я там напутал с правами немного, на самом деле можно всё без root'а собрать. Потом может быть сделаю видео по-проще. Некоторые утилиты нужно будет скачать из сети (если команда не будет найдена). Это касается создания md5sums файла.
