Since coming to Maplesoft in 2003, I've kept a notebook of "gems" I've gleaned from consulting with the programmers in the building. I call it my "Little Red Book of Maple Magic." It really is red. The first spiral-bound notebook was little, and it was red. When it overflowed, I moved the notes to a red ring-binder. But it's not so little any more.

Here's a fun video that we discovered today.  A Maple user and music composer posted a video featuring one of his songs. As the description of the video states, it includes "Maple animations of parametric surfaces mixed up with modulo functions rendered in cylindrical coordinates."

The animations start at the 1:12 mark of the video. 

I'm posting here because between the time I started writing and the time I wanted to post my answer, the question is no longer available (may be a network problem, a withdrawn question, don't know)

The first problem is that you write ASAP in the title of your question, very uncool.

Another problem is that you use "else if" instead of elif, with "else if" you need one "end if" for each if but with elif you only need one "end if" to close the...

Introduction to this blog

From time to time, I find some problem with Maple. It is not always Maple's bug, sometimes it is just my mistake.

I am used to use "Submit Software Change Request " form, but I dont know how to trace my requests (and I even dont exactly remember which bugs I posted). Thus, I decided to publish my troubles in this blog.

Unless stated otherwise, all the troubles I specify bellow are obtained on the Mac OS X 10.5 PPC platform using Maple 14.01 ...

Hi! Russian Maple A Center running exactly 10 years.
Anyway, now it is visited daily by about 4000 students.
It is a pity that I develop the center alone.
But still, someone advertises Maple in Russia.
Paul Goossens, how are you?
Best regards!

Fine if it can be managed.

Additionally it would be of great help, if threads can be viewed in their
original semantical ordering, i.e. as they have been meant and created
by the contributors (and not through 'ratings').

If not many are very hard to read, some still almost useless.

We are currently working on a set of updates to MaplePrimes, which you can expect to see rolled out sometime during the first quarter of this year.  Most of the changes have been taken directly from your comments and feedback about MaplePrimes, so thank you very much!

Some of the changes you can expect to see include:

• Down-voting will be removed entirely.  Up-voting will continue to work as it does now.
• An advanced search feature will...

I just got a smartphone, amazing. Wouldn't it be wonderful to have a mapleprimes app to conveniently view and post messages from a smartphone or a smartpad or whatever? Any plans to set one up? (I'm on the android platform)

The other suggestion/question I have is: any plans (by Maple or others) to make a Maple calculator widget? I'm currently using RealCalc, which is great, but it  doesn't have the advanced term-grouping capabilities of the Maple calculator.

While doing some Maple plotting I found myself asking why a high-end scientific computation application like Maple, which is capable of essentially very high ("arbitrary") precision floating-point computation, sometimes makes only crude use of hardware precision plot drivers. I looked around a bit, and found that and related issues are not restricted to Maple.

Let's look first at Maxima. Here's my first example, in Maxima (not Maple) syntax,

     I suppose that Maple 15 is now in the stage of beta testing, but I have not served as a beta tester for a few years.

     Those scientists and mathematicians who apply Maple in teaching mathematics, science and engineering or who use it in their research naturally wonder what will be in store in the next release to complement and to extend the features in preceding releases.

This post will explain how to configure the compiler and other tools that will be necessary for you to build the External Calling examples that will come in later posts.  This is an advanced topic and so this post is fairly complex.

First, I am going to be using the compilers via the command line, so you will need to familarize yourself with the terminal program on your particular OS.  You'll have to do this for yourself, but here are a few starting points:

Windows

Apple

I am going to assume that Linux and Solaris users are familar with using the terminal.

For Linux, Apple and Solaris, I am going to use gcc as the compiler.  For Linux you should use your distribution's package management system to get it, for Apple you need to install Xcode and for Solaris, well, gcc is probably already installed or you'll want to talk to you sys admin to have it installed (or if you are your own sys admin, you probably know how to install gcc for yourself).  For Windows, you need to install the Windows Software Development Kit.  If you already have a copy of Visual Studio C++ (Express or Professional) installed, then you already have these tools.

I am also going to use the "make" program to manage the building of the examples, thus you will need to install a version of make as well (you won't need to learn how make works unless you want to modify the examples).  I will be using gnu make, which should be easy to install on Linux and Solaris (similar to how you installed gcc) and it is included in Xcode for Apple.  For Windows, use this:

http://gnuwin32.sourceforge.net/packages/make.htm

Installing 32 bit make on 64 bit windows is fine.

Now you'll need to launch a terminal.  For Linux, Apple and Solaris this should be easy, on Windows go to the Windows SDK folder (or Windows Visual Studio folder) on the Start menu, there should be an icon for Windows SDK Command Prompt.  Click that to launch the terminal.  This version of the terminal has the environment configured to run the compiler.

On Windows you'll also have to add the location you installed make to your path, which can be done on 32 bit windows like this:

path=%PATH%;C:\Program Files\GnuWin32\bin

and on 64 bit Windows like this:

path=%PATH%;C:\Program Files (x86)\GnuWin32\bin

assuing you used the default install location for make.

You can test this by running "make" in the terminal.  If everything is set up correctly, make should run but not find a Makefile and it will raise an error.  If the path is not set properly, make won't be found you'll get a message saying that.

Path not set properly:

C:\Program Files\Microsoft SDKs\Windows\v7.1>make
'make' is not recognized as an internal or external command,
operable program or batch file.

Set the path:

C:\Program Files\Microsoft SDKs\Windows\v7.1>path=%PATH%;"C:\Program Files (x86)
\GnuWin32\bin"

Make is now found, but there is no makefile in the current directory

C:\Program Files\Microsoft SDKs\Windows\v7.1>make
make: *** No targets specified and no makefile found.  Stop.

As a final test, I've attached a small example (test.zip) that contains a Makefile and a simple source file.  If you extract the files to a new directory, go to that new directoy in the terminal and run make (with make added to the path as described above) it should build an executable (test or test.exe).  You can run the executable by executing "test" on the command line.

By default the Makefile is configured for Windows, so Windows users won't need to change it, however other users will need to comment out the

WINDOWS=true

line in Makefile by changing it to

#WINDOWS=true

I know this is a little confusing, especially if you are not familar with the command line interface, therefore I encourage you post replies if you have problems.  Hopefully we will be able to answer your questions.  Once everyone has figured out how to get this simple example to compile and run on their system, the upcoming external calling examples will be (relatively) easy.

Good Luck!
