I use an editor, which knows (hard) line breaks, for example MS Word:

"^p> " (note the blank!) to be replaced by "^p" (which is the code for a line break).

Setting all control characters to be visible I also can recognize 'strange' texts (which sometimes happens by copy & paste)

I have not tried for 'piecewise' outside the plot (I do not speak MMA), but I would not expect Maple to translate a somewhat complicated plot command from MMA (even if it would be nive to have such - it is not the intention to translate from other CAS).

Actually I alraedy would be happy, if Maple would translate from Matlab in a readable way ...

I would agree - may be for nested comments a tree at the LHS (like at Google) could be helpful for orientation

Adobe Flash Player Multiple Vulnerabilities, considered highly critical, see the 3 pages at secunia.com/advisories/35948/

That's one reason why some do not want to use it

Even before taking the quotient (not trusting Maple for 0/0) with M12:

'(G(1-h^2)+1)'; diff(%, h);
limit(%, h=0, right);
                                   2
                            G(1 - h ) + 1


                                  1/2
                                 2

(G(1-h^2)+1); diff(%, h); 
MultiSeries:-limit(%, h=0, right); simplify(%);

                                  1/2
                                 2
                                 ----
                                  2

Editing others posts? Without going into legal aspects: if afterwards there
is only the slightest impression, that the originator wrote that text and
had not explicitely accepted that  I find it really outrageous.

And if he is asked and accepts a suggested change he probably can do it himself.

Better organization for some threads is desirable, sure, but not at that 'price'.

At least you need something not to attribute that to a specific (natural) Person,
some collaborative thread ab initio.

That says not that much to me, except the very last part  "My advice: determine the one key aspect of company fit, in our case technology, and use that to determine your correct course of action. If the fit doesn’t exist, then save everyone a lot of time and money and walk away. And remember, what doesn’t kill you, makes you stronger."

My English certainly is not good. But it sounds like a "fare well" of a CEO.

Alec,

I have a problem in using that (modifying to BA:=module() option package
for Maple 12.02 to make it work):

  with(BA): Digits:=53:  # want to apply it for double precision

  x:=evalhf(-1+2^(-50)); # which shows, that evalhf is not exactly double
  X:=convert(%, binary); # write that as binary, 53 binary digits

  # now use the module for binary arithmetics
  X1:=B(1+X);
  X2a:=B(X*%);
  X2b:=B(X*X1);;

    X1 := 0.11100011100011100011100011100011100011100011100011100
    X2a := -0.00011001010010001011000011111100110101101110100111011111
    X2b := -0.11001010000100011100110100010010011110010011110001000 10^-6

  # now check, converting to deciamls again:

  # this is ok
  1:=1+x; convert(X1, decimal, binary): evalhf(%);
                                        -15
                           x1 := 0.88 10
                         0.888888888888888840

  # but then
  x2:=x*x1; 
                                                 -15
                  x2 := -0.8799999999999992256 10

  # I do not understand the results for both of these, they are wrong 

  convert(X2a, decimal, binary): evalhf(%);
                        -0.0987654320987654128

  convert(X2b, decimal, binary): evalhf(%);
                        -0.0123333456666789993

this sounds like an idiotic excuse for a bug  - sorry for the harsh words, but that must not happen

PS: though I understand a vendors need, I always asked myself what happens with activation (for then older versions) if the company has passed

Well, this thread seems to be an effort caused by www.mapleprimes.com/blog/jacquesc/bored

And thus not bad.

But you should face reality: if one enters MaplePrimes through it main URL (which I avoid, using 'tracking") you have to face that the last user contributions are jpmay from May 2009 and Jo Riel from March 2009. The rest is some kind of advertising.

Or in a provocating form: even Maple finds the content not interesting enough. Which is scaring, as it would not change that much by technical modifications to this forum.

What I see through answers to your enquiry: those who are present whish to have it alive. Beyond technical things.

Availability. Please care: this is advertising for Maple. It should have down time below 2 h / quarter (that is expensive, yes).

please re-think your question: I did not say it is a correlation matrix ...
