New Beta SMath Studio 0.99.6617 is available!Tiny, but powerful mathematical program with WYSIWYG editor and complete units of measurements support. It provides numerous computing features and rich user interface translated into about 40 different languages. Application also contains integrated mathematical reference book. Changes introduced in current buildImprovements- SS-144: Mode to insert special symbols into equation implemented using Ctrl+K (Ctrl+Shift+K is also supported);
- Added possibility to work with unicode symbols using built-in functions;
- Units added: Fr (statC), Fd (faraday), nmi, au, ly, pc, mmHg, inHg, month, week.
Corrections- Rendering background grid on print out fixed when Grid is turned off in Worksheet editor;
- Multiple worksheet rendering/interaction issues fixed;
- Cursor location fixed when set after space char in equations text entries;
- Fixed situations when collapse/expand button on Area didn't work on click;
- Stability of the Worksheet export (f.e. to PDF) improved;
- Moving of mouse cursor over the region corrected for Pages view layout;
- Exception on Print dialog close within SMath Viewer fixed;
- Printing from SMath Viewer restored.
Miscellaneous- Interface translations updated;
- Refactoring.
Download Best regards.

Now we can write even the argument separator in subscripts like in eurocodes (not like the decimal separator that changes with settings, but close enough for daily work)  ![2018-02-12 19_04_15-SMath Studio - [Page1_].png](/forum/resource.ashx?a=22172&b=2) Edited by user 12 February 2018 21:04:42(UTC)

Hello, Davide!

It is pretty important f.e. in Russia:

Creating a variable right on the form SmathViewer Accidentally discovered - it 1. Error 2. Future plan 3. Or so intended - undocumented opportunities And this trick works only when there are variables before and after our variable "fdsf" Перевод: Создание переменной прямо на форме SmathViewer Случайно обнаружил - это 1. Ошибка 2. Планы на будущее 3. Или так задумано - недокументированные возможности Причем этот трюк работает только тогда, когда есть переменные до и после нашей переменной "fdsf"  Gif-Animation

Technically i thnk 6617 is implementing vectorize correctly. If you want to achieve the results from 6484 you need to apply the vectorize function to the input of rgb2dec as shown in the attached example. vectorize (1).sm (9kb) downloaded 51 time(s).Edited by user 13 February 2018 19:12:43(UTC)

Hello, Alvaro. Originally Posted by: Razonar Hi. Which goes to be the correct answer? Thank you very much for this report! I have investigated issue and see new version shows incorrect results (I have introduced this bug during work on refactoring). I have found the reason and just fixed it. Now results are the same as in 6484. I will release new SMath Studio version soon. Best regards.

- it
1. Error
2. Future plan
3. Or so intended - undocumented opportunities Heh. This is not something I planned to implement. I would say this "feature" is introduced accidentally  At least it is a first time I see it. And I even not sure what to do with it now... Best regards.

I don't know why this vectorize function confuses me so much. Could someone explain to me how this function operates? I tend to think of it as a similar to the "dot" . command in Matlab. For example in 0.6484 shown below. I don't see how calling vectorize either inside the function or outside the function produces the same results, but calling it both inside the function and outside cancels its effects. I'm sure my misunderstanding comes from ignorance on how SMath works behind the scenes and order of operations. But to me the behavior in 6617 tends to make sense.   |

Since it was introduced [Smath 6179] and 100's time I used it, it works same as Mathcad 8 Pro <= 11. It is an element wise operator, seemingly universal similar to all matrix/vector algebra ... for instance 2d, 35 rotation. Does it work ? Yes and no as you put it. As simple as it looks, follows some rules depending upon the result style. Jean  vectorize (1).sm (96kb) downloaded 48 time(s).

Hi. Yes, vectorize is similar to the dot operator in matlab, but also like map in maple and /@ in mathematica: ever language have a way to operate "element by element" in matlab speak, or over the "head" of structures, in the others. SMath "structure" are always arrays, and could be confusing the behavior when the vectorize operator operates over "arrays of arrays". Fortunately, SMath is more congruent than mathcad, which behavior was unpredictable between versions:   Here is the maple's map and mathematica /@:   Best regards. Alvaro.

You may hit the wall from "vectorize" ... Explain => Mathcad vectorize operator take interpolation functions, Smath does NOT, thus the vect operator fails. Unlike Mathcad, Smath linterp, ainterp, cinterp are NOT scalar functions ... demonstrated in the attached. This nuance will save you growing more gray hairs.
