Sébastien Brisard commented on MATH-581:
----------------------------------------
As for my taglet, the idea is to embed a little piece of javascript in order to
render the mathml code in a html page (instead of xhtml). So it is very (very)
lightweight, with two drawbacks
* portability : the javascript code would be different for every single browser
(tested on firefox for the moment)
* file management : each equation must be kept in a separate file : this is not
a big concern, all files are stored in the {{doc-files/}} directory. I also
have implemented a taglet called {{@inlineMathML}}, where the MathML code is
typed directly in the {{*.java}} file, but it applies only to very small
formulae, since the source file gets very quickly blotted. Anyway, as I said,
I'm very happy to contribute this code if you think it can be of any use. We
can start a new JIRA ticket on this.
I think I kind of agree with Gilles' point of view on javadoc sticking with
ASCII. However, the code I develop at work is numerically oriented, and I do
not have enough time to write both a thorough Javadoc *and* a math-oriented
doc. So I decided to go for a detailed Javadoc, with MathML formulas.
BTW, I only used a tip found
[here|https://developer.mozilla.org/en/Mozilla_MathML_Project/Authoring]. I
remember having found on the internet the corresponding code for IE.

> Dear all,
> this issue has already been discussed on the forum. The idea is to implement
> the most popular linear iterative solvers (CG, SYMMLQ, etc...) in
> commons-math. The beauty of these solvers is that they do not need direct
> access to the coefficients of the matrix, only matrix-vector products are
> necessary. This is goof, as sometimes it is inetficient to store the
> coefficients of the matrix.
> So basically, before implementing the iterative solvers, we need to define an
> interface slightly more general than a matrix, namely LinearOperator, with
> only one basic operation: matrix-vector product.
> Here are a few interfaces and abstract classes that do that. Nothing fancy
> yet, I just wanted to have you advice on the implementation before I commit
> some solvers.
> I thought these classes could go in a package
> org.apache.commons.math.linearoperator, but really, I haven't got a clue...
> Best regards,
> Sebastien
