  • Powerful tools to support dynamic calculation. Excellent!

    by Omar Panta Carranza

  • Es un imprescindible para el día a día. Muchísimas gracias Mr Andrey Ivashov.

    by Ángel Álvarez

  • Great tool for all engineers. It's very user-friendly and has lots of functionalities that can be further extended by installing plug-ins (it takes just a few clicks, no need for tedious file manipulations). SMath can operate on units, perform symbolic calculations and many more. Also, it has very clear interface and all formulas can be entered just like you would do on a piece of paper. What's more, the software has great community of people willing to help with various issues.

    by Jacob M.

  • I am using it everyday for my professional work. Thank you so much!

    by Tien Nguyen

  • Fantastic free software. Have used it for several structural calculation reports

    by Martin Kynde

  • I hope you keep on developing this great software! Thank you very much, it is easy and very efficient. If someone could help you to bring it closer to a nice text editor, it would probably replace Word for many engineers and other scientists.

    by Dimitris

  • If you are thinking about getting MathCAD for your business or personal use you may want to try SMath Studio first. SMath Studio is a free math program with easy to use intuitive "paper-like" interface. If SMath Studio meets your needs then look no further and consider donating to promote further development of this great program. On the SMath Studio forum, the developer and forum community are very receptive to help questions, bug reports, and feature requests.

  • I'm a student of civil engineering and SMath has become an invaluable tool for "by hand" calculations of my assignments. I can't believe other students are still using MS Word and a regular calculator.

    by Filda

  • Excellent tool...

    by Munawar Jakhro

  • May God reward the developers, for filling the vacuum left after MathCad. Thank you very very much.

Very good! 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) Clap

One more benefit here is that we are not limited in units names now. 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"

Создание переменной прямо на форме SmathViewer

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.

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.

Heh. This is not something I planned to implement. I would say this "feature" is introduced accidentally Good 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.

... some examples

Observe the matrix/vector rules ... M*rotation ... NOT rotation*M
Cholesky solver is not commutative ... + examples vectorize => please feel free !

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 /@:

... the few examples above make you confident.
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.
