Gilles updated MATH-521:
------------------------

    Attachment: example_LaTeXLet.tar.gz

This is an example IMO clearly demonstrating that a LaTeX equivalent of those 
ASCII structures would be

# incomparably easier to decypher in the source file, and
# be even more pleasant to read in the browser as a graphics file rendered by 
LaTeX.

I've just discovered "LaTeXLet" a tool that does what I had talked about on the 
ML a few weeks ago: A custom taglet that allows LaTeX in Javadoc and renders it 
as PNG.

Please have a look at the generated HTML doc (in the attachement) when run on 
the input file "DocSample.java" (also included).

> (1) The "guess" method throws "OptimizationException" when the algorithm 
> fails to determine valid values for amplitude and angular frequency.
> There are no test showing how such a situation can occur.
> Moreover, since this procedure is used to provide an initial guess to an 
> optimizer, it is better to pick any values for those parameters (e.g. zero) 
> and let the optimizer proceed from that initial point.
> (2) The class javadoc seems very thorough in explaining the algorithm, but is 
> quite unreadable in the source code, making it fairly useless for checking 
> how the code complies with the comments. I think that this explanation should 
> go in the user guide (and leave a mostly "plain text" outline of the 
> algorithm, referring to the guide for details). [Does the format of the user 
> guide allow such tricky (ASCII "art") constructs?]
