Hi. Thanks! Very much!

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

Any example about what that means?

Also, I see that this error persists:

Can you show an application of it ?
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.

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.

Thank you! Fixed.

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.

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.

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)"

Here my attempt to convert an expression with operators to an expression with binary or unary functions only
