First, note that Maple interprets pi as a greek character with no special connotation. For the mathematical constant, use Pi instead.

As for the simplification of cos(Pi/2) versus cos(Pi/10), some rational multiples of Pi are treated automatically, while others are not because the resulting expression could be rather large. If you explicitly want that, try

convert(cos(Pi/10),radical);

I suppose you are running Maple 12. The Code Editor had a problem with such characters; it turned them into octal notation upon reloading. It has been fixed in Maple 13.

Very good decision. I hope we will see the same when MapleSim 13 is due.

You might also consider using the symbol option, e.g. A:=Matrix(3,3,shape=symmetric,symbol='a');

So you see the symmetry immediately.

If possible, do not use linalg anymore. It is marked 'deprecated' and is no longer maintained, AFAIK. For hints on porting to the newer packages, see ?examples,LinearAlgebraMigration.

If memory serves me well, the contract between Maplesoft and Casio ended about 10 years ago. You might find such a PDA on the second-hand market, but any laptop with current Maple is highly preferable.

I purchased one of last few Cassopeia A-23G. The hardware and operating system (Windows CE 2.0) were rather weak, and the Maple V version that came bundled with it had severe restrictions as compared to the full version for "ordinary" computers. See www.maplesoft.com/support/Casio/index.aspx.The b/w display was hardly readable even at maximum contrast, and the battery was defective after a few months. Earlier Cassiopeia models (A-21 et.c) were even worse, I was told by a Casio representative.

AFAIR, it wasn't possible to run the CF card with Maple in other PDAs. The Cassiopeia used a Hitachi SH-3 CPU.

Let's be glad this product was discontinued. ;-)

If you see a  "Use hardware acceleration for plots" entry in the Tools > Options > Display dialog, uncheck it, then click one of the Apply buttons, then re-do the plots. This solved the problem on some machines at least. Replacing the JRE should be independent of that, though I can't tell for sure.

This error message usually means that the installer file is corrupt (although it seems to suggest something else). So delete it and download it again. If the error remains, contact Maplesoft Customer Service.

Well, my posting was probably too short. ;-)

What I meant was: you can let Maple handle such events in almost any way you like. E.g. with

NumericEventHandler(invalid_operation=exception):

arctan(0,0) will raise an error. Or you could supply your own handler procedure instead of 'exception' in the above command. That proc could emit a warning and/or return any special value you prefer.

Admittedly, this is a bit unintuitive at first, but also very flexible.

Hi Alejandro,

when you call arctan(0,0), Maple toggles the NumericStatus(invalid_operation) flag from false to true, so you can catch this special case. The ?arctan help page should hint at this feature, I think.

If there is a Fortran to MATLAB translator (I'm not aware of any, but some aspects of these languages are quite similar), you should check out the new MATLAB translator in Maple 12 to import that intermediate code. See e.g. ?FromMatlab and ?FromMFile for more details. This facility does not cover 100% of MATLAB's language features, but it's extensible by the user.

That just confirms that all good things in this life are free.

Alec, here's a page that you might like: www.maplesystems.co.uk/ (scroll down a few lines).

I had misunderstood you, and now found your files in the Recent Files list. (MaplePrimes is really confusing sometimes.)

Sorry, I don't have the time to investigate, though. It's 8pm here. ;-)
