Please, Uni or Omorr, could you translate the text on the image on first post?

Thanks a lot

Thank you for your efforts on this but, unfortunately, there is no way for me to understand how is this working and how should this plugin be used .

Regards,
Radovan

Ok. I'll make simple video tutorial.

Hi Uni, I was trying again with your plugin, but I have a problem: This plugin is not compatible with windows 7

Hi Uni, I was trying again with your plugin, but I have a problem: This plugin is not compatible with windows 7

Try to change the environment variable TEMP (TMP) to c:\temp (short path). And run the program with administrator privileges.

Hello uni,

By changing TMP,TEMP variables it works now for me (WinXP(32))
Just could not believe it was that simple

[MATH=eng]maple(dsolve(diff(y(x),x)+5*y(x)≡3*x,y(x)))=y(x)={3*(-1+5*x)+25*exp(-5*x)*_C1}/25[/MATH]

[MATH=eng]maple(int(1/x,x))=ln(x)[/MATH]

Thank you,
Radovan

EDIT:
On Win7(64) (I changed TMP,TEMP variables) the following error appeared - first picture attached.
I have the Administrator privileges, of course. If I run SMath as Administrator, error apperaed - second picture attached

Hello,

Just a reminder on this post about wrong mixed derivatives

See please the results using maple plugin by uni -(unfortunately, it seems it is not working on Win7(64) or I do not know how to make it work) and by SMath. SMath is doing this wrong and I hope this will be corrected in the next SMath release.

Regards,
Radovan

Radovan, plugin doesn't support nested expressions yet (see file mvr4.txt with intermediate calculations). This means that you can not use functions, because mapledos.exe not see them (need to finish, I hope it will be in the next release):

27.09.2012 18:33:09 [->] diff(diff(f(x;y);y);x)
27.09.2012 18:33:09 [->] C:\Temp\tmp8C7.tmp:
interface(quiet=true);
writeto(`C:\\Temp\\tmp8C8.tmp`):
sys := proc() { args[i] $ i = 1..nargs-2 }; end:
ans := diff(diff(f(x,y),y),x):
if ( whattype( ans ) = `exprseq` ) then convert( cat( `mat(`, substring( convert( [ans], string ), 2..-2 ), `,`, nops( [ans] ), `,1)` ), string ); elif ( whattype( ans ) = `set` ) then convert(cat(`mat(`,substring(convert(map2(op,2,[ans[i]$i=1..nops(ans)]),string),2..-2),`,`,nops(ans),`,1)`),string);else convert( ans, string ); fi;
quit:

27.09.2012 18:33:13 [<-] C:\Temp\tmp8C8.tmp:
diff(diff(f(x,y),x),y)
27.09.2012 18:33:13 [<-] diff(diff(f(x;y);x);y)

As for the 64-bit version, I'll think about it.

Update: mvr4_20120927.zip

If you want to use function from SMath Studio write this: int(sin(x),x) or maple(int(sin(x),x)) - it will be the same.
But If you want to use function from Maple V R4 (DOS) write this: maple("int"(sin(x),x)) it will not be equivalent to maple(int(sin(x),x)) (preprocessing is done before calling maple()).

P.S. I still think how to do better .

Wish you all the best about it.

By the way, is there any chance that plugins you and other good people made could be available in one place and not scattered through the Forum . I suppose that at list new forum like "User plugins" could be made and all the user plugins available for using to be put there. As far I know all the plugins are in the "Samples" among many other topics.

Maybe Andrey could open a new "User plugins" Forum for instance

Radovan, I added a link in the signature.

Ah yes, I see - did not see that sorry

Thank you very much - I will keep your link as a reference for all your very useful plugins

Thank you very much,
Radovan

Try this one: mvr4_20120926.zip. In the plugins folder there is a log file of transformations: mvr4.txt. Don't forget to check it periodically.

Thanks. Testing ...

Hi. I dislake M54IV (the last version which use old Mathcad versions). But love M5R5. That version have a different notation for strings, more like the new versions of others softwares. Also, it works in Windows 3 version, for 16 bits, but with the extension for 32 bits. Even I don't understand how use the semicolon in the uni examples, here is the result replacing mapledos.exe, and lib and licence folders with this version.

Could you show the contents of the file mvr4.txt?
Many years ago there was even a website called "Maple bugs". It had a lot of them.

Sure, here it is.

I forgot that I also have cmaple.exe. Thanks for reminding me, I'll change the plugin to support the "Maple V Release 5". As for the semicolon, you can just write a comma. It depends on the settings in SMath Studio.

It can be great, and I agree with you about to not convert smath in a kind of fronten or front cover to call others programs. But in the meantime that have not some functions, like indefinite integrals, maybe the best way in call some external program could be use a wrapper function (like Eval or Parse) inside of smath, where each user can configure it's oun kernel (maxima, yacas, ...).

Ah, and thanks for remember me the smath configuration.

Can´t call the function with two args. (Pila vacía = empty stack)

Regards.

Alvaro.

statement :d

Wait for a while, I'll change the plugin and then you'll can use it normally.

jajaja. It's late and it's raining. Thanks.
