There is a Mma translator which translates Mathematica code to Maple code.  I believe you will have to go to Mathematica to get a Maple translator into Mathematica.   

There might be a few people here who use Mathematica enough to help you with a conversion, and similarily there might be a few people on the mathematica forum to help you with a Maple translation. 

It sounds like you want a general conversion application, unfortunately one most likely needs to take care of the conversions one by one. Please provide the worksheet you want translated if you would like to get started.

It is in my Maple startup, but strangely it's never appeared there in previous versions of Maple.  I leave the startup Maple as is, so it always opens the startup file.  The only thing I do when opening Maple is open a new worksheet and close the Start.mw startup file, I should probably just remove it from the startup.  However it's only just now I've realized Start.mw showing up in the recent documents list.  Just wondering if that was a software change or fix?

ImportMatrix won't work using HTTP:-Get in my case. 

But it looks like String surgery is the only way with Maple 18. 

For interest and programming sakes, how can you get this to work in Maple12?  HTTP returns nothing.  Anyone?

Are you saying Mathematica has twice the functionality?  Not that it really matters.  What matters is if the software you have can do what you want it to.

What's interesting is that scrolling keywords graphic.  That would be neat to see coded in Maple.

Ok if I use something like a vector I can add it to the rest of the DataFrame block.

<<RowLables(a)[..]>|<convert(a,Matrix)[..,1..4]>>

Funny, you need the [..] on RowLabels to work the way I want it to.

So now the difficulty has become making the RowLabels into a normal Matrix or Array column. 

@tomleslie ok thanks. RowLabels is the key.

The first column got labelled with a time index.  And by using RowLabels(a) I can pull the time column out.

@max125 it is an excercise in google translate.  Luckily not too much work for me to do for you.  I have uploaded the worksheets translated in english.

@Carl Love what is harder is given an answer of sqrt(6)/6, how is it manipulated to 1/sqrt(6) ?

Fair enough.  That will do.

I can't see why you would have to convert the radical to a floating point for it to work. 

Is there a situation where sqrt of a some random number would cause sign to fail?

Curiously how did you convert 1/6* 6 to just 1/ 6

Using remove to remove the sets containing k[d2]=k[d1] is from Sa1 is

remove(s->true in map(has,s,k[d2]=k[d1]),Sa1)  # remove sets containing k[d2]=k[d1]

 

Strangely remove(s->false in map(has,s,k[d2]=k[d1]),Sa1) doesn't produce the other two sets as I think it should. 

map(has,Sa1,k[d2]=k[d1])
                 

If I read the command that I just wrote down, I would take that as remove the set NOT containing k[d2]=k[d1]
                            

@tomleslie Equation number and labels are 1 to 1 until you use a plot in your worksheet. 

So the workaround is to use the Retrieve command generated by the context menus in worksheet mode.

Should I submit a problem report?
