What sort of functionality would this give over and above what ToInert & FromInert give? acer

You might start out by ready the help-page that comes up in Maple when you enter this, ?external_calling After that, you might follow the pages referenced at its end, in its "See Also" section. acer

I never found the help for InstallerBuilder to be very useful. It's not very full, especially concerning what appears to be ability for scripting. What I have had success with is the InstallerBuilder:-Interactive() routine. However, what I've used it for in the past is simply to "Add" files (there's a button for that). I add files, specifying where it is to grab them from, and where it is to install them when run. It outputs a single .mla file, which contains all the bundled files. When this .mla is opened in the GUI, a maplet gets run, with a few panels, just like an installer. The bundled files may contain other .mla files, .hdb files, example worksheets, dynamic/shared libraries, etc. Once or twice, I've had it create and bundle its own uninstaller, too. I suspect that it was designed, originally, for 3rd party MapleConnect products, so that authors could create their own installers. I don't know if it's still used. One thing that I find interesting, is that Maple seems to find directories like /toolbox/XXXX/lib and /toolbox/XXXX/bin. and append libname and PATH with them automatically. Does this not make such locations ideal for placing user-authored packages, especially when bundled/redistributed for others? I also find interesting the idea that a .mla archive may be autoexecuting in some way. Something clearly gets created, which does the work. So, if the InstallerBuilder is not to taste, I wonder whether one could find and utilize the tech behind it regardless. acer

The .mla maple archive format itself supports some of what you mention. It can contain more than just .m files. It can contain image files, other .mla archives. Maybe any other file, I think. A .mla archive can also be set to execute and unpack files, with a popup progress maplet, when opened in the GUI. See ?InstallerBuilder . Or run InstallerBuilder:-Interactive() . acer

Sure, the bad behaviour might be on the part of the webmail system. But a compressed worksheet format might sidestep it nicely. Thanks for your details, acer

Thanks for the information, Scott. But it doesn't sound so promising. It'd be reasonable to surmise that this has been known for quite some time already. acer

If that explanation is accurate (and it does sound plausible) then there may be a great many other users who also experience the problem. If that's so then it'd be well worth fixing. acer

That's very interesting. Now all that I wonder is why I get plotting error in the maplenet client, when I try to follow the link in the posting. (I could download the .mw,.. but I wanted to try the viewer.) I get a little pop-up, whose "details" show a lot of java exception messages. Is there a certain recommended jvm version to have for this? Right now, my Linux machine says, $ which java /usr/local/java/j2sdk1.4.2/jre/bin/java acer

Hello Jacques, Could you give a reference to that algorithm? Would it suffice to use LinearAlgebra:-Nullspace in the usual way, for each eigenvalue? acer

Another benefit of having large projects' maple source in text files is that one can run mint against them. That is a syntax and code analyzer for maple. See ?mint for the help-page. On Windows it's called wmint.exe , and allows one to browse, select, and open a test source file. (Often the extension .mpl is used for such files.) The mint program may not be as up-to-date as it could be, but it's still useful. acer

The ability to re-use the code can be done with another refinement. Instead of using `read` on the source file one can `savelib` it to a .mla archive. (See ?LibraryTools, or ?savelib). Once the code is saved into a .mla library, then in any other worksheet or session one can access it simply by appending to `libname`. (See ?libname) Once comfortable with that, the following observation can be useful. If the code has been abstracted out of the worksheets that run it, then one may never need to simple `read` the source file into any session except the one in which it gets `savelib`d. A natural followup is to then hard-code the appropriate savelib/LibraryTools commands right into the end of the source file. Or comment it out when not being actively developed. One could even write a batch file that simply runs the source file with the commandline interface. When run, it saves the program to the right .mla. The tasks are then nicely split: - editing with your favourite editor - saving the source to a .mla archive - adding the right libname to worksheets. But these actions can all be run concurrently. I usually have a restart in my worksheet, too, so that I can edit, re-load, and re-run examples, all without having to close out my worksheet session. Another refinement is to have a "standard" place that you put your .mla archives. One can probably create a desktop icon that starts maple with some extra -b options, so that that location is automatically appended to libname. acer

What exactly do you mean, when you say that Maple 11 is too slow on your machine? Could it be that it's simply the Standard (Java) Graphical User Interface (GUI) that is slower for you, in Maple 11? If that's the case, and if you are using Windows or Linux/Unix, then you might try using the "Classic" interface instead. On Linux/Unix that is started with a command like `maple -cw`. On Windows it should have its own icon on the desktop, and if you didn't install the desktop icons then the binary is maplew.exe I believe. acer
