Best WYSYWIG math software, with outstanding cost/effect factor! In some areas even better thought than it's commercial oponent (auto complete, very big plugin database, small program size etc). Highly reccomended.

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

Great free software. I use it for calculations of civil structures. Thanks a lot.

This is a great piece of software! I use it on my Linux machine. With best regards from Munich, Germany.

Excellent alternative to MathCad and it's free!

by Marco Finlay
I have been wishing for a sensible alternative to the free version of MathCAD for a long time. I find such software a crucial tool for writing technical-paper-style documents with live formulas and units carried throughout. I am so happy to have found SMath Studio as it is not just a completely free, fully featured alternative, but I find it to be much better in that it is tiny, is easier to use, has nice community support and has nice expandability by others (through plugins). It has features I've always wanted like setting of number of significant digits (not just number of decimal places), easier typing of subscripts, better plotting (via the X-Y Plot plugin), ability to include other SMath files (like my own units definitions), the very innovative and helpful "dynamic assistant", the ability to assign values to variables *after* the writing of a formula, no watermark across each page, and many other improvements that I have yet to discover. Since I am so pleased, I just donated $100 which I feel is a more reasonable amount for software like this. Thank you, Andrey!

Excelente software para los cálculos de ingeniería, muy livano, pero bastante robusto a la hora de realizar cálculos; y su plataforma en la nube es buena.

Superlative !!! good job !!! Congratulation

To show some results I've made available equrep(3) function which is hidden from auto-completion list and other places. It demonstrates possibilities to manipulate with complex structure of different equations. I'm not sure if anyone interested in this function at all, but under the hood it is used almost for every calculation in the program. This function has three arguments: - First is a given equation (anything to manipulate with); - Second is an input for manipulation rule; - Third is an output of manipulation rule. In other words it allows to apply some manipulation (described in two last arguments) to an equation (from the first argument). Some examples: Do not forget to set Optimization=None if you want to see exact result without any extra numeric or symbolic optimization. Best regards.

Maybe, this might simplify restructuring of terms inside plugins. As it seems, the function does not preprocess it's first argument. The definition of c isn't during the call of eqnrep when running the sheet step by step. I see that the structure patterns should be unevaluated otherwise you would rely on having the variables therein being undefined in the sheet. How about a function or a flag enforcing preprocessing? equrep.sm (6kb) downloaded 19 time(s).

Расчеты делаю в Вашей программе, затем вывожу на печать в формат PNG и вставляю результат в Word. Возникает проблема с блоками, отмеченных как "Запретить вычисление". Раньше над ними (в правом верхнем углу) был прямоугольник, сейчас они отмечены серым фоном. А с ним как раз и беда. Что можно сделать? На просмотре так: На печати так: Как видно не все блоки напечатаны, причем некоторые из нерасчетных были всё же напечатаны. Ранее (когда не было фона) таких проблем не возникало. Для печати использую виртуальный принтер pdf24. Стандартный экспорт в PNG формат не делит на страницы, так бы им пользовался (там кстати проблем нет). Пока вышел из ситуации с помощью скриншотов. Костыль конечно, но ничего не поделать. Edited by user 08 November 2019 21:47:42(UTC) \| Reason: Not specified

The issue is that many times, we define the variables and further down the calculation shows the equation ... that I'd like to manipulate. I tried setting optimization to none and symbolic, both failed

The space between the equations has some variables "defined". Maybe what I'm looking for is a feature request. I have the same issue with Maple plugin. Essentially, I'm transferring a hand calculation and wanted to show all the steps in order. It does not make sense to isolate and manipulate an equation that is not used for 3 pages ... it's out of sequence and out of context This screenshot is valid for both optimization=symbolic and none

No need to scratch the right ear with the left hand. Further: your stuff must be tracable/accepted/visible.

Rank: Advanced Member Groups: Registered Joined: 13/09/2011(UTC) Posts: 66 Location: Kolkata Was thanked: 9 time(s) in 9 post(s)		Hello Andrey and everyone, I wonder if, since equrep(3) now gives access to smath's internal representation it should be possible to get this "engineering" way of writing equations, discussed in many posts since many years, like here: https://en.smath.com/for...umbers-in-equations.aspx to summarise: a:=2 b:=pi p:=ab ------------------- symbolic equation =23.14 ----------- equation with variables replaced by their values (with control of their format, accuracy, etc.) =6.28 -------------- numerical result This is a numerical equivalent of the visual control that was available to civil engineers at the time of graphics statics. It gives an immediate feel of the magnitude of values, their accuracy and relevance for the result. We can easily do as below: a:=2 b:=3 p:=ab ----------------------------- (definition) equrep(p:=ab,x,x)=23 ------------- (no optimisation) equrep(p:=ab,x,x)=6 --------------- (numeric optimisation) and by not displaying input data: p:=ab 23 6 However the middle equation becomes unreadable as soon as we have values that are not round numbers, so we also need to control the format of the values of variables in the middle equation, and to insert some "=" in-between. This is much beyond my ability! If anyone had some idea how to do something close to that, that would help some structural engineers!
