version in pkgsrc. There are many, many bugfixes, better compliance with
S3/S4, and many additional statistical analysis functions added to the
base library. There is also an improved (faster) garbage collector and
support for dynamically sizing the memory used by R. The full summary of
changes may be found on the R Project website.
BUILDLINK_PREFIX.<pkgname>. This allows buildlink to find X11BASE packages
regardless of whether they were installed before or after xpkgwedge was
installed. Idea by Alistair Crooks <agc@pkgsrc.org>.
checked correctly. Can cause scilab to crash instead of printing a warning.
Patch came from Giuseppe Allodi <Giuseppe.Allodi@fis.unipr.it>
posted to comp.soft-sys.math.scilab.
bump to 2.6nb1.
Changes:
Version 20.1
MA and kinds rebased on new package Properties (which grew out of the
old activeattr.py file previously in MA). Masked arrays can now be
pickled.
Properties provides a easy-to-use method to have a name act
as if it is a attribute of the class but be able to control reading,
writing, and deleting of that attribute via methods of the class.
Applied patch that fixes errors when Python is pymalloc-enabled (dmcooke).
Applied patch to add new support in LinearAlgebra for symmetrical
eigenvalue problems. (Allesandro Mirone)
Applied patch to fix comparisons to None in MLab.py (jbmoody).
Found and fixed another one in RandomArray.py.
Applied suggested fix by Mark Hadfield to let setup_all.py work on
systems where Python is installed in a directory path that contains
a space.
Version 20.0
Redo setup.py so that binary windows installers for Numeric, FFT, MA,
etc. can be made automatically. Packages LALITE and RANLIB merged back
to top level. Adjustment for BLAS in setup.py.
Documentation of Numeric module made more compatible with pydoc.
argmin/argmax/argsort/sort errors with axis specs fixed (bug #233805)
-- also made them capable of handling args that can be converted to
arrays by adding an array(a, copy=0) at the start.
Fixes sum, product, cumsum, cumproduct, alltrue, sometrue to deal with
zero shape and to take arguments that can be converted to arrays.
MA: See changes.txt file in MA for bug fixes and improvements.
New option for average to return sum of weights.
Fix bug in putmask so that it handles targets of type object.
Because of reference counting issues this is done in Python, not C,
and would not be more efficient than doing your own loop, but we
include it for completeness.
In Packages add draft implementation for PEP 0242, Numerical Kinds.
Add PyArray_CopyArray to the API (Thanks to Dave Grote).
Add defines for cygwin.
In arrayobject.h, add static declaration to importing API pointer.
May solve OS X problems.
Fix bug in FFT packages, added new test. (Thanks to Warren Focke)
Added __deepcopy__ method equal to __copy__ method. Throws an exception
if the target is an array of type 'O'. But this at least allows non-object
type arrays to be copy.deepcopied. If someone has time they can do this case.
* What is new in gsl-0.9:
** There is a new system of vector and matrix views. Any code using
vector and matrix views will need to be updated.
** The order of arguments of the view functions involving strides have
been changed to be consistent with the rest of the library.
** The ode solvers have been reorganized.
** There are new eigensystem routines for real symmetric and complex
hermitian matrices.
** The linear algebra directory now includes functions for computing
symmetric tridiagonal decompositions and bidiagonal decompositions.
** The svd routines now include the Golub-Reinsch and Modified
Golub-Reinsch algorithms in addition to the Jacobi algorithm.
** The interpolation directory has been reorganized and a higher-level
"spline" interface has been added which simplifies the handling of
interpolation arguments.
** IEEE support is now available on OpenBSD.
BitVector is a fairly extensive and fast BitVector class for Ruby.
Handles sequences of up to 2**32-1 bits (about 500 Mb). Implemented
as a wrapper around Bit::Vector version 6.0 by Steffen Beyer.
shared libraries.
Changes between NTL 5.0c and 5.1a
Some minor fixes and additions.
Completely backward compatible.
* Added a routine LatticeSolve() for finding integer solutions to
linear systems of integer equations.
* Modified the stragey used by the LLL() and image() routines in the
LLL package to deal with linear dependencies. The new strategy
guarantees better worst-case bounds on the sizes of intermediate
values. I'm not sure if it will have any serious practical impact,
though.
* Added some "partial ISO modes" so that one can use some of the
features of Standard C++, even if ones compiler does not yet
support all of the features.
* Bug fix: routine determnant() in mat_GF2.h was not visible to the
linker because of a typo in mat_GF2.c.
* Made a "smarter" script for selecting the GetTime() function. This
fixes an installation problem on Cygwin/Windows 95 platforms. I
hope it doesn't create more problems than it solves, though.
* Added some extra documentation for installation under Windows/MS
Visual C++.
* Changed some names like c_lip.c to c_lip_impl.h. This should avoid
some potential installation problems.
* Throw away first 256-bytes of arc4 streams to improve quality of
the pseudo-random number generator. This may change the precise
behavior of some programs.
* Other minor, internal modifications.
CXXFLAGS, and LDFLAGS by the buildlink.mk files so remove the extra
definitions to add them from the package Makefiles. As advised by the
bsd.buildlink.mk file, also ensure that the buildlink.mk files are
included prior to defining any package-specific CFLAGS/LDFLAGS to ensure
that the buildlink directories are at the head of the compiler search
paths.
Use BUILDLINK_INCDIR, BUILDLINK_LIBDIR for locations of linked headers
and libraries. Create a variable BUILDLINK_TARGETS whose value is the
list of build-link targets to execute.
* What is new in gsl-0.8:
** The build process now uses the latest libtool and automake
** The library should now compile with Microsoft Visual C++
** Portable versions of the isinf, isnan and finite functions are
available as gsl_isinf(x), gsl_isnan(x) and gsl_finite(x).
** The definitions of GSL_POSINF, GSL_NEGINF and GSL_NAN no longer
cause divisions by zero during compilation.
** The gsl_interp_obj has been renamed to gsl_interp
** The poly_eval and pow_int functions have been moved from the
specfunc directory to the poly and sys directories.
** The Chebyshev functions are now available as an independent module
in their own directory.
** The error handling conventions have been unified across the
library. This simplifies the use of the special functions.
** A full CBLAS implementation is now included for systems where ATLAS
has not been installed. The CBLAS library can also be used
independently of GSL. The organisation of the BLAS directories has been
simplified.
** IEEE support for HPUX-11, NetBSD, Apple Darwin and OS/2 are now
included.
** The library now includes implementations of log1p, expm1, hypot,
acosh, asinh, atanh for platforms which do not provide them.
** The convention for alloc and set functions has changed so that they
are orthogonal. After allocating an object it is now necessary to
initialize it.
** There is a new module for estimating numerical derivatives of functions
** There is a new module for handling data with ntuples
** The histogram lookup functions are now optimized for the case of
uniform bins, and include an inline binary search for speed.
** The Chebyschev coefficients for the QAWO algorithm are now
precomputed in a table for efficiency, rather than being computed on
the fly.
** There are several new sorting functions for selecting the k-th
smallest or largest elements of a dataset.
** Iterator functions are now available for permutations,
gsl_permutation_next and gsl_permutation_prev.
** The function gsl_complex_xy has been renamed gsl_complex_rect
** The API for simulated annealing has been changed to support search
spaces in which the points cannot be represented as contiguous-memory
data structures. gsl_siman_solve() now takes three extra arguments: a
copy constructor, a copy function and a destructor, allowing
gsl_siman_solve() to do its work with linked data structures. If all
three of these function pointers are NULL, then the traditioanl
approach of using malloc(), memcpy(), and free() with the element size
is used.

This is an implementation of a VSIP Library (Vector/Signal/Image
Processing Library) as defined by the VSIPL Forum for a CORE profile.
The TASP_VSIPL library is an effort to produce a VSIPL library
suitable for demonstration and early development and testing of VSIPL
code and ideas.
The Tactical Advanced Signal Processing Common Operating Environment
(TASP COE) effort is striving to produce a common operating
environment for signal processing throughout the Navy and DOD for the
COTS environment. VSIPL is thought by TASP to have a good chance of
becoming a standard signal processing library for many vendors who
supply DOD high performance computing products. For this reason TASP
is supporting the VSIPL effort.
This is the TASP VSIPL Core Plus implementation of VSIPL. Core Plus
includes all the functionality of the core profile plus most floating
point Vector and Elementwise Operations not required by the VSIPL Core
profile. The additional functions include such things as matrix
elementwise add and multiply.
The TASP VSIPL code is required to be freely available for any
use.
