Grazie tanto per lo splendido lavoro. Io lo uso per i miei calcoli di elettronica. Большое спасибо за замечательную работу. Я использую его для моих вычислений электроники. Thank you so much for the wonderful job. I use it for my electronics calculations.

by Vito BLASI
This has been a great step up from Excel. Extensive (and extensible) support for engineering units opens a new world for well documented everyday analysis. Thank you!

by Mike Graham
excellent

by Mohan
Congratulations!! This software is amazing!! An almost complete substitution for Mathcad!!

by Hervandil Sant'Anna
SMath Studio is an excellent free tool that can be used by anyone ranging from students to professionals. I have used it since back in college, and it has been an invaluable tool for speeding up my productivity and design quality both in my work and hobby life. Thank you Andrey!

by William
Thanks Andrey Ivashov for this wonderful tool that you provided. It is designed very well and the best opensource alternative to MathCAD available.

by Walter
Imagine combining Microsoft Word with the ability to compute every time you press equals. Best application for your engineering documentation needs!

by Michael James Quidilla
Amazing, well-done, useful tool. A small donation was sent your way. This small comment of praise is a follow-up.

by Jason H
Excellent alternative to MathCad and it's free!

by Marco Finlay
I strongly encourage professionals who use the software for commercial purpose to donate. SMath Studio, in my opinion, is better suited for documenting engineering calculations than MathCAD Prime 3, which is commercially developed, and is considered to be the software of choice by many. As engineering professionals, we all pay yearly professional license fee; if we donate a fraction of that fee to Andrey it will let him to continue working on this extremely useful and functional tool. Thank you, Andrey! Long Live SMath

An image is good enough. Thanks ... Jean Just to make it clear: equrep() function is not something I'm spending time on to create/support/improve. This function appeared as a demo of the updated symbolic core of SMath Studio. This function is an interface to the new functionality. You can use it or not, but it demonstrates possibilities of the symbolic simplifications SMath Studio provides. Unfortunately it has at least one issue which is hard to fix. I'm doing my best to remove a bug, but if it will be too hard maybe I will revert my changes and use stable (which is used in latest stable version of the application) symbolic core again. So it is not about equrep() function it is about core of the program, its performance, possibilities, behaviors etc. If you are remember, all the calculations in SMath Studio goes through symbolic optimization, so it is pretty important. Best regards.

No matter what I do in the contex menu, the border can't be switched off. Neither is there a change in the GUI, nor is the xml attribute changed. If I load this file in 7251, then I can switch off the border, this is both visible on the canvas and in the xml entry. Once I save that (second file), this can be opened by 7542 and the change is respected. And you guess it, the border can't be switched on again. Thus, actually there is no wrong file, just wrong GUI behaviour. 7542 displays existing files correctly. Just no access to this one setting. I leave out the maxima draw region, as this might prevent reproduction without maxima installation. border 7542.sm (8kb) downloaded 21 time(s). border 7542 then 7251.sm (8kb) downloaded 23 time(s).

Thank you very much. Fixed now. There is one issue with the plug-in: invalidation of the region is not requested after menu item usage (it must be done by plug-in) so borders will be visually switched only after region redrawn, f.e. after scrolling or focus in/out. Best regards.

Issue is fixed in the latest stable version I have just published. equrep() made less powerful, so it will leave an equation as is in cases where error is possible. Like your example. This is temporary solution but it is required to continue development without serious stoppers. In future I will continue working to make symbolic engine more smart. Best regards.

Best regards. This also seems to be the cause for delayed re-draw after editing operation (you have to get focus off the image to see the changes). Very valuable hint!
