I have used MathCAD since 1997. Loved it. I used to work for the Nuclear Industry in Canada, and we had these long calculation sheets fully written in MathCAD. As an independent researcher, I also had a student version which I could simply purchase from a campus bookstore as a CD. A few years later, disaster struck! A greedy corporate entity purchased MathCAD and destroyed it. A tool created for engineers by engineers with engineering in mind was destroyed by MBAs with only money in their minds. I was helpless until I discovered SMath. I was amazed at how SMath could do so many things with the installation file being just a few MB! And Andrey simply gave it away to us for free!! SMath has truly filled the void left by the now-extinct "old MathCAD". The fact that SMath is not bloatware and gives us researchers exactly what we need are reasons enough to call Andrey a genius. My dear Andrey, many of us are out there in various parts of the world quietly blessing you for helping us do our research calculations. You are a noble soul with a spirit that cares for a better world. Trust me, you have in your own way made our world a better place to live through SMath. God bless you. I shall surely donate an amount as a symbolic gesture for your great work. Please continue to serve the world and may God bless you with good health, a long life, peace, prosperity, and a sound mind that scientifically contributes for as long as you live and pave the way for your glorious legacy long after we are all gone. more...

Très bon logiciel de calcul, avec de nombreux plugin pour tous les usages. Une fois qu'on s'habitue, on ne peut plus s'en passer. Je le recommande vivement. Outre les fonction mathématiques, Il est possible d'utiliser de nombreuses bibliothèques, comme par exemple la bibliothèque Coolprop pour les données thermodynamiques, ce qui permet d'avoir un outil très évolué pour faire et expliquer des calculs très rapidement. more...

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 more...

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 16 time(s). border 7542 then 7251.sm (8kb) downloaded 18 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!
