  • Excelente alternativa para reemplazar a Mathcad, me ha ayudado mucho en mi carrera de Ingeniaría Civil, me suscribí al plan anual, gracias.

    by Cristian Yamid Pérez Peña

  • 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.

SMath Studio plug-ins (all plug-ins...)

The functionality of the program can be expanded through the installation of plug-ins created by third-party developers and companies, as well as those prepared by the SMath LLC team. Most plug-ins are open source and can be modified if necessary.

Hi. Thanks! Very much!

"equrep() function supports variables/functions replacements now."

Any example about what that means?

Also, I see that this error persists:

Yes, this is a main reason why I can't release stable version of SMath Studio now. I'm working on this issue right now.

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.

For this application [Julia], timing kills Smath ... Oh !

Maybe it is a bug maybe intended I don't know;
On 7542 for underlined text regions, spaces are not underlined.
No problem for letters, numbers, punctuations, etc.
Writer regions don't have this issue.

I can't switch on/off any more the border of image regions (and also fo Maxima draw regions) in 7542.
In 7251 this still works. It also works for documents produced in 7542.

I can't reproduce this issue locally. Please could you upload a files (one with correct behavior and another with incorrect)?

I attach two files. The first one is created in 7542. 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.

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.

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.

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!

...


I post that question because interpret that then equrep works replacing f by sin in this example: "equrep(3+f(x),f,sin)=3+f(x)" but now I see that the correct way is "equrep(3+f(x),f(a),sin(a))=3+sin(x)"
