Ann: Statistical distributions / Mathematical Special Functions

This package consists of 3 related components, and we're now seeking further 
feedback on these before the final push prior to a review:

Statistical Distributions
~~~~~~~~~~~~~~~~~~~~~~~~~

Following feedback from the previous preview,  we have re-organised
so that distributions are now C++ classes.

See the docs and especially the tutorial for illustrations on how
this will be useful in real life.

We would especially welcome feedback from those with experience of
using statistics, and indeed from professional statisticians who are
probably not Boosters.

Mathematical Special Functions
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

These are currently focused on those functions that are useful for
statistical applications:

Floating point classification.
Gamma/lgamma/digamma/beta/erf/erfc
Ratios of gamma functions
Factorials
The incomplete gamma and beta functions.
The inverses of the gamma, beta, and error functions.
Derivatives of the incomplete gamma and beta functions.

Statistical Distributions / Mathematical Special Functions: revised URL's

Since some people have had problems accessing the previous URL's given, the 
library is now available from the following locations:

www.johnmaddock.co.uk/toolkit

Or

http://freespace.virgin.net/boost.regex/toolkit/index.html

Or

Go to the Boost Vault at http://boost-consulting.com/vault and cd into the 
"Math - Numerics" directory.  Note that the code and documentation are 
separate downloads.

In addition there is the subset of Boost-1.34 used by the lib here: 
http://freespace.virgin.net/boost.regex/toolkit/miniboost.zip  Please note 
that the lib will not build with Boost-1.33.1 since it uses some parts of 
Boost.TR1.

And finally...

Bleeding edge cvs access is available via the Boost-Sandbox: 
http://sourceforge.net/projects/boost-sandbox/

Once you have checked out the sandbox you will need to do a:

cvs update -r math_toolkit

at which point everything should disappear except the current math-toolkit

[boost] Review of Generic Image Library (GIL) begins today, Oct5, 2006

The review of Generic Image Library (GIL) begins today,
October 5, 2006, and continues through October 15, 2006.

Please download the library at: http://opensource.adobe.com/gil.
Minor change are being made regularly (daily), so check the site  
often for
updates.

I highly recommend viewing the 55 minute Breeze
presentation describing the library at:
http://opensource.adobe.com/gil/presentation/index.htm

A tutorial is available at:
http://opensource.adobe.com/gil/gil_tutorial.pdf

A design guide is availage at:
http://opensource.adobe.com/gil/gil_design_guide.pdf

Description:

The Generic Image Library (GIL) is a C++ library that abstracts
the image representation from operations on images. It allows
for writing the image processing algorithm once and having it
work for images in any color space, channel depth and pixel
organization, or even synthetic images, without compromising
the performance. GIL has an extension mechanism that allows
for adding extra functionality. Two extensions are currently
provided – one for image I/O and one for handling images
whose properties are specified at run-time.

[review-results] pimpl_ptr

Unfortunately I must say that the pimpl_ptr library will not be part of 
Boost at this time. The results where decidedly against the library in 
the proposed form. A few points about the library where clear:

* Many want to see a pimpl_ptr in Boost.

* The proposed design was considered to not do enough towards addressing 
the handle-body idiom within C++.

* Some of the ideas, the policies, where both liked and disliked. Which 
raised the specter of the lack of a policy pointer.

Hopefully we will see this idiom addressed in some near future.

Last, I must apologize for the late results. But I must thank Ronald for 
the gentle prodding :-)
