Try to typeset

normal(1/((omega^Omega/a-1/2)[a,sqrt(2)][1/2]-(zeta+iota)[-y][-1,1]+(xi+Xi)[alpha[1/2]]));

in your favourite version of Maple. What's the "best" way to typeset this in LaTeX so that it looks 'best'? The renderer here on primes gives:-1/(-(omega^Omega/a-1/2)[a,2^(1/2)][1/2]+(zeta+iota)[-y][-1,1]-(xi+Xi)[alpha[1/2]])

It's fairly ugly, but at least the baseline alignments seem to be ok, even though the fonts are way too small (and fuzzy too).

I am trying to compare the speed of a program run using the Maple interpreter, with that of the same program writen in say Fortran or Pascal and then compiled and run on the same PC. I have done this using an FFT program and have obtained a figure of approximately 840 : 1, which is much larger than the factor of 10 or so, that I expected. Does any one have either any comments about this, or perhaps any benchmarks of there own

A Boston-area comedian by the name of Steven Wright used to say, “It’s a small world, but I wouldn’t want to have to paint it.”  Well, that tells you more about my sense of humor than about geography, but it’s true – it is a small world.  And it’s getting smaller and smaller.

What one usually means by “small” in this context is that it’s easier to get around.  Not just because travel is faster in the days of jet planes than it was in the days of caravans, but it’s because foreign places aren’t as, well, foreign as they used to be.
Just 30-ish years ago (ish is too many) I had to bring enough cash with me wherever I went to cover the needs of my trip because ATMs didn’t exist.  I couldn’t (well, wouldn’t) call home because it was horribly expensive.  That is if I could figure out how to use the phone.  I didn’t stay in touch with home at all because there was no email, no IM and no internet for Facebook or Twitter or anything else.

I've had this happen to me a few times now: I'd hit Reply to a particular post, then click inside the Subject box to enter something, and instead I'd find myself staring at a new tab loading Facebook.  It's not always Facebook - earlier it was some place I'd never heard of, like Deeb or Geed or some such.  I'm on a Mac Pro running OS X.4.11 and using Firefox 3.08.  Anyone else run into this sort of thing?

Dear all,

I think I came over a quite fundamental error in Maple 10's CodeGeneration package. Even without knowing Matlab, it should be clear that the conversion into Matlab code goes wrong here:

restart;
tt :=  x^(1/y) :
with(CodeGeneration):
Matlab(tt);

produces

  "cg = x ^ 0.1e1 / y; "

Even Maple 13 does not recognize Excel 2007 files (*.xlsx).

Excel 2007 files can be saved as Exel 2000 files before using the Import Data Assistant but I think it is not up to date to do so.

A few mornings ago, I drove to the office, bleary-eyed and still waiting for my first liter of coffee to kick in.  I parked, exited my car, and started walking to the entrance.  Someone a few meters ahead of me held the door open, but let go while I was still about a meter away.  Judging the closing speed of the door, I thought I had enough time to sneak in.  However, during the latter stages of its closing sweep, it suddenly sped up, and slammed shut. Not yet being suitably caffeinated, I uttered a small curse, damning the door and all its close mechanical relatives, and reached for my key fob.

The help page describes it as a technology preview. I never use this because my mouse isn't precise enough.  What do you think, what purpose will it have later, besides finding missing symbols ?

Hello there,

I got myself Maple 13 recently and tried to plot   > plot3d(abs(SphericalY(1, 0, theta, phi)), theta = 0 .. Pi, phi = 0 .. 2*Pi, coords = spherical);
 

But the plot doesn't look like it should at all. Since I'm pretty sure that the spherical plotting is very well developed I believe there is a mistake in in the definition of SphericalY.

If there was truely a bug, what can I do to get this fixed as soon as possible?

Regards,

Sven

Is there a convenient way to express a 2nd or higher derivative, say in an eval statement, so that it is not confused with an expression containing an exponent?

I recently ran into an interesting twist on the infamous Maple anti-pattern:

# A very garbagey way to build a list
l := [];
for i from 1 to 10000 by 100 do
    l := [op(l), isqrt(abs(floor((5000-i)/2)))];
end do;

A lot of users fall prey to this method of building a list rather than using :

# generate a list without extraneous garbage
l := [seq(isqrt(abs(floor((5000-i)/2))),i=1..10000,100)];

Modelica is an open language for (lumped parameter) modeling and simulation and is generating a growing following, especially in Europe. Modelica is also at the heart of simulation tools like MapleSim. We are generally not making a big deal of that fact and as a result we have a regular stream of actual and potential customers asking us why we are not more vocal about our use of Modelica. Do we not believe in open...

It was twenty years ago in May that I started with Maplesoft (known then as Waterloo Maple Software) in a tiny office at 608 Weber Street North in Waterloo, Ontario. After having done my graduate work under Maple co-founder Gaston Gonnet, I was invited to join the fledgling company as Technical Manager and the first full-time employee.

I've been using Maple 12 on a Mac for a few months and came up with some suggestions:

(1) make it possible to add one's own symbol combinations to the Favorites palette

(2) allow symbols in the Favorites palette to be re-arranged

(3) permit redefining key-bindings so the Home/End keys send the cursor to the beginning/end of the current line, as on the PC (and in this posting box), etc.

(4) have keyboard equivalents for basic actions, e.g. Esc for the Cancel button, Cmd-[ or equiv. for the PreviousPage button, etc.

Hi,

for pictures like this i'd like to have an arc tool in the drawing part of Maple. One that lets me create a cleaner  arc around the angle u. Here I used the pencil tool instead.
