Thanks to the function Exports, it is possible to see the differents functions and modules which are in a module.

For example, I find in the module GetMultibody a module called GetLGM which permits to conduct some linear graph analysis. I'm interested by this module.

However, to my knowledge, I didn't see any help on this module.

How can I do so as to understand the inputs to give to the functions of this module in order to use the functions of this module ? In other words, how it is possible to use functions from a module when you don't have any help at your disposal ? 

Thanks a lot for your help.

I have three procedures with calling struture:


    > call B (argseq)

    > call C (argseq)

     > etc code

     > return results

end A()

Procedures A, B, C are defined in a single MAPLE .mw worksheet, and each time I use them I have to reload them by pressing return.

Please can you suggest the best course of action?  I have been reading about modules but am not certain that A knows about B and C in the dame module when it calls them

Can anyone help please?





In a simulation code I use "module-factory" concepts (where a module has a proc; the proc in turn returns another module that has all the procs one wants) a fair bit to keep the code readable and maintainable.

At this point I have the code mostly doing what I want it to, but the run time could be improved (read: I want it to go faster). So I have started working with CodeTools:-Profiling. Quickly I am running into the Profile() function apparently not being able to deal with my generated procedures.

Is there a way out? In other locations I read about procs to be profiled having to be in a Maple library; this is the case for my routines (it all is in a big module with procs, submodules etc.). I'd rather not rewrite the code extensively just to allow profiling (in particular I would not really like to abandon the module-factory scheme), but of course I can do some modification.

Any suggestions?

is there a simple maple package template that i can look at?

I wrote a module with about 30 procs, i want to make it into a package but I don't really know where to start.


all i need is an existing package that i can simply


  • rename the title
  • swap the code with my own code
  • swap the example with my own example

I have written a (rather extensive) module, which I can load without problems if I run it in the following way:


restart: libname:="C:\\PathToLib",libname; with(NameOfLib);


Note that the above is all in one line and executed at once. If, however, I load the library like above, but line by line, the loading fails, giving the error "Error, Did not recognize this structure's syntax".

How can there be a difference...

There are a few ways to view the source of a Maple procedure, such as by using the commands  showstat and print. And these work as usual for the exports of a module. But for procedures which are declared as local to a module these methods do not work right away since by default modules' contents are opaque.

One way around this is to change a setting, by issuing kernelopts(opaquemodules=false) prior to attempting...

Hi, im Gabriel from chile, and probably my english wouldnt be very good :P.

Im working on a problem that needs to be solved numerically, its a set of coupled non linear equations. Im succefull in finding the solution given a set of initial conditions, but the problem I have is when I try to save those solutions.

I want to save them in a .m file to fully recover it when I start the session again (it take some time in find the solution, and I have to iterate the...

Hi, To see the body of a procedure in Optimization[Interactive] module, i use this method: interface(verboseproc = 2); kernelopts(opaquemodules = false); print(Optimization[Interactive][BC]); but "too many levels of recursion" Error occurs! Note that this method works for other procedures in this module, for example test it for Optimization[Interactive][InittoText]. What is problem for "BC"? and what is the solution? thanks.

The following interaction with Maple's Excel link came to my attention today.  I thought it had many interesting points that lead to insights about Excel and Maple that are worth sharing. 

hi! i get the following error when i try to see response to my thread coeff problem in maple 13. Fatal error: Call to undefined function getgif() in C:\xampp\htdocs\modules\maplemath\maplemath.module on line 30 how can i fix it?


I am maintaining a C++ application that requires Maple code generation features to produce C code.

This application uses the EvalMapleStatement (kv, statement) function, where 'statement' is actually a CodeGeneration[C](...); command.

The application has worked correctly before, and the generated code has been incorporated as modules into other applications that make use of it.


Some time ago I started to write my own modules.
I've a problem with a module calling an export of another one. Both have the "package" option.

The first module, Math_Tools_ex export a "diffindice" procedure. I copy here the relevant part of the code:


export diffindice, doublederivcov,Dimensione,mix, Test_Symmetry, Double_dag ;
export Coords,A,M,G, Abstraction;
global X, c, dimensione,abstraction;
