There is more, working with matrices [3D, PseudoInverse ...]
Just a RemToDo.
The "Matrix Editor" Ecxel style is lovely, indeed.
At the end of this compendium, you will find a much
superior tool, directly from Smath, just make it
resident in the project work sheet and keep going.

... few more under construction.
I noticed something terribly grave while working the main sheet.
Explain: while working, Some "illegal" code [apparently], Smath toke
... very happy working well. Bad luck, on closing the work sheet
it zapped the entire work [turn it all blank at reopening]. Oh ! Hell
Good think, most of it I could recuperate from previous attached.

Any fellow experienced such a nightmare ?

I Underatand, it's a big chunck for Smath, but peanut Mathcad 11
I still have a 100 MB Mathcad 11 WS [graciously made dead by PTC]

Comments/suggestion/typos: always appreciated

Unfortunately, this happens...

I've made this proposal, anyone who want to support/improve it, you have to register in the Bug Tracker System.


BTW seems you have found something that I have to change...

Thanks Davide for visiting and commenting. The "Why not nested" is simply because on closing,
either XP or Smath don't save the work sheet settings, completely.

I know about Autocad "AutoSave" but don't use AutoCad.
In my case, I didn't try XP Restore because of the time inprecision: it might have done nothing !
On delicate work sheets like "Matrix Treasury" I also save as copy,,, that one was scrapped too !

Your "AutoSave" proposal [link above] is quite welcome. Now convince Smath Developpers.
