You can install the "Special Functions" plugin, which has a Clear() function as you need.

Actually this plug-in is built-in into the installer package.

If SMath would allow to clear variables inside a matrix,
that would be an answer for your request.
But it does not, so this is a dead-end.
For now, you have to make all your variables an element of vector/matrix,
if you want to clear all of them in single command.
Or manually clear them one by one.

Hi. I think what the user request is a function similar to "clear all" in Matlab.
Given that include is capable of collecting all the names of the variables of a worksheet as the "whos" command of Matlab would do, perhaps the include code can be used to implement the option to delete all the variables with Clear( "all" ) or something similar.
Best regards
Alvaro.

Clear(■,■,■,■,■) ...
clears the system in cause [variables, vectors, matrices]
Clear(x,y,z,m,ω)=1 are evaporated from the system.

remove ... you mean clear for reuse ?
Option Find [Ctrl+F] finds numerical single value,
it takes only one search at time, greek not from
palette but copied from palette
Does not distinguish math regions from text.
Not much use for Find.
If the letter is a vector just ignored.

Yes Razonar, probably that is the OP's request.
He doesn't want to write every variable into Clear().
Just Clear(ALL) and puff, all defined shall be cleared.

Hi, sorry to resurrect the thread, just chiming in to say that I would really love a Clear(ALL) function too.
Often it would be nice to use a one SMath file to make multiple repeat calculations but not being able to clear the variables makes repeat calculations extremely risky.

The Clear(All) will not clear matrix/vector that are not resident (isolated).
Fromm observation, in that case, set XY the matrix XY:=0
That clears the global system calculation.

Not all variables/parameters are declared.
Many reside @ the kernel level, not recognized by Clear(,,,)=
I have an instance that can't be renewed by Clear(,,,)=

Good morning!
So there is a Clear(All) function? How is it used?

AFAIK, there is no Clear(All) ... what is All ?
Clear(,,,) also restores the built-in.
Cheers ... Jean.

Hy,
is there any update on such a "Clear(All)" function?
Would be really helpful to have it like this
a:=5
b:=6
Clear(All):=1
a=?
b=?
Thanks for answers

Build your system algo style complete wrt parameters
Collapse in utilities, top document.
Now, you are in-situ command line mode ...
Nothing to clear. Just plug parameters in each command line.

There is not a Clear(All) function.
No method is applicable to remove all variables at once.

There is not an update, yet.
Unfortunately, I guess none shall appear on horizon soon.

This works!!!
Thanks for the beta update.
What would you think about revising output string?
Instead of "1", it can be;
arg==1 --> "All cleared"
arg==2 --> "Variables cleared"
arg==3 --> "Functions cleared"

You're welcome, glad it seems to work correctly on first try. I still have to check carefully the (2)nd option, since as it is now it deletes "anything that is not a function" (including some low-level stuff).

Usually I prefer a binary output, since can be used inside if/else functions independently from localizations, future enhancements of descriptions, and string comparision issues.
I'll think about it.

If you have discretized [x,y,z ...] in part 1 of project
as that part 1 is complete ... Clear(x,y,z) for next part of the project.
Assume part 1 & part 2 are constructed around 5 parameters.
If you ClearAll(,,,,,) past part 1
You have to re-install those 5 parameters that over-ride
themselves from the new ones.
