Over on the usenet newsgroup comp.math.soft-sys.maple, someone asked about using Maple's overload facility to redefine the operators such as `*`, `+`, etc.

The difficulty for the submitter is that while overload (and option overload for procedures) can provide enhanced operators for new routines, it doesn't affect routines saved in the Maple Library which already have their bindings. Overloading does not subsequently change the bindings of the operators when used in (most all) Library routines.

One way to try and get around this is to actually redefine the global operators. And since overload is on topic, one can still use it in the replacements that one writes.

In order to redefine global operators one must first unprotect them. They are protected for a very good reason. If the replacements are not adequate then Maple can fail in a multitude of ways. It's a case of caveat emptor.

Has anyone tried the technique used here, to run Maple 12's 32bit Classic GUI with the 64bit Maple 12 kernel binaries, on Linux?

Should I try and update it to work with Maple 11 or 12?

It looks like some symlinks would have to change or be added, relative to the way that I did it for Maple 10.

Has anyone ever tried to do a similar thing on 64bit Windows?

Hi there ! The attached worksheet has a good review on the theory of Limits and Continuity of functions that have two or more variables.

The attached worksheet has a specially designed tool that helps you evaluate the limits of really complicated multivariable functions.

 

Please feel free to ask questions.

For a single pair of left single quotes, ?name is clear:

Any valid Maple name formed without using left single quotes is precisely the same as the name formed by surrounding the name with left single quotes.

So this is fine:

`x`;
                      x

But what about multiple left single quotes? This help page also states:

If you have a standard math, complicated expression in your Maple worksheet that you would like to include in a blog in this venue, what's the most economical way to copy & paste it?

When inserting standard math into a text region, Maple insists on converting even simple decimals like 0.01 into scientific notation.  Can I suppress that?

Here's a first working shot at an external, programmatic mechanism for opening .mw worksheets/Documents as new tabs in an already running Maple Standard GUI session.

This involves a `sh` shell script, runnable in Unix/Linux/OSX/cygwin. Maybe someone could post a MS-Windows .bat batch file equivalent.

The basic idea is this: you have a GUI session open. But you want to be able to open other .mw files in that session without having to go through the GUI's File->Open menu every time ...

Maple's Standard GUI has context-sensitive menus. Those are the menus that appear when one right-clicks on a output (or input, in a Dcoument).

Those context-menus can be customized.

Below is an example which adds a new submenu. The new submenu is populated automatically according to the types of thing found within the object itself.

It's an alternative to a menu-item that already exists, which shows up as "Help on Command". But that existing item only...

One way to enhance a package is to add to Maple's context-sensitive menus  some new menu entries which utilize that package's features.

In Maple's Standard GUI, context-sensitive menus (a.k.a. context-menus) appear when the mouse is right-clicked over (input or output) 2D Math expressions.

For a package implemented as a module, new and relevant context-menu entries can be created inside the module's ModuleLoad export. That will cause the new menu entries to be created (automatically...

Large or involved projects may involve Maple modules which rely upon each other. Routines in one module may call routines in another module. Interdependence of modules can have a direct bearing on the available means of successfully utilizing the `use` functionality. In certain situations, some of the ways to utilize the `use` statement can be problematic.

Some such situations, and workarounds, are illustrated below.

The basic description of the `use` statement functionality is,

If x -1 is regarded as the difference of two cubes, can Maple factor it?

Can Maple graph the Dirichlet function?

f(x) =   {0,   if x is rational
            {1,   if x is irrational

Hello

i have a question regarding the Compiler:-Compile Command in Maple12
under linux i got this error message when trying to compile the example:
> y := proc( x :: float ) 2.3 * x end proc:
> cy := Compiler:-Compile( y):
Error, (in Compiler:-Compile) possible installation problem:
GNU C compiler (gcc) not found in your command search
path (PATH). You will need to restart Maple after ensuring that gcc
is installed and adjusting your PATH environment variable.
>
> cy( 1.1 );
cy(1.1)
but the compiler is installed in /usr/bin and maple knows the path:
> getenv(PATH);

Hi, how we can get the min of two real-valued piecewise continuous functions as another piecewise function. To me Maple responded with min(fn1,fn2), which I dont need. Plz hep.

Hi, I want to carry out set-theoretic operations on real-line intervals.  For example

> [2,5] intersect [3,7];
 

Is there any package available for this and interval arithmetics?

Thanks.
