Don't use __sighandler_t at all, it is not standard and at least on
DrgaonFly means something completely different. Also change the typedef
to match what signal actually expects. Fix some more minor glitches
for DragonFly.
This version contains several minor fixups and removes a couple of bad
bugs such as NA-handling of mean() for integer vectors.
Changes 2.3.0
This version contains several changes and additions, mostly incremental.
Xfractint draws a wide variety of fractals. Xfractint is a port of the
IBM PC program fractint. Xfractint has online documentation which
should be referenced for most operation information. Note that the
online documentation is from fractint, and does not always accurately
describe xfractint.
Add locale message for sv. Bump revision.
Fix configure to detect libintl correctly on NetBSD.
Don't remove the entry again, fix the script if necessary!
Changes:
- Excess variables cleanup of taylor command.
- Changed argument of push command from an equation number to an equation
number range.
- Added easy selection of equation spaces, just type the number at the
prompt.
- Allow flist command when Mathomatic is compiled as a library.
all PEAR packages to php?-pear-* and all Apache packages to ap13-* or
ap2-* respectively. Add new variables to simplify the Makefile
handling. Add CONFLICTS on the old names. Reset revisions of bumped
packages. ap-php will now depend on the default Apache and PHP version.
All programs using it have an implicit option of the Apache version
as well.
OK from jlam@ and adrianp@.
Changes:
A number of minor changes.
Fixes and improvements to the Mathomatic Command Reference.
Upgraded clear and set commands to accept more than one argument.
Gave real and imaginary commands a useful argument.
Fixed a sloppiness in command line parsing in function get_range().
Code cleanup.
* Performance improvements for Intel EMT64.
* Performance improvements for large-size transforms with SIMD.
* Cycle counter support for Intel icc and Visual C++ on x86-64.
* In fftw-wisdom tool, replaced obsolete --impatient with --measure.
* Fixed compilation failure with AIX/xlc; thanks to Joseph Thomas.
* Windows DLL support for Fortran API (added missing __declspec(dllexport)).
* SSE/SSE2 code works properly (i.e. disables itself) on older 386 and 486
CPUs lacking a CPUID instruction; thanks to Eric Korpela.
Cutting planes of two new classes were implemented: mixed cover
cuts and clique cuts. On API level this feature can be enabled
by setting control parameter LPX_K_USECUTS passed to the routine
lpx_intopt. In glpsol this feature is available through the
command-line options --cover and --clique. For more details see
the reference manual.
Now the routines lpx_read_mps and lpx_read_freemps support LI
bound type. It is similar to LO, however, indicates the column
as of integer kind.
Changes:
Improved matho-primes by making primes buffer variable size.
Added "set factor_integers" option.
Removed "simplify poly" option, it was rarely useful.
Code cleanup, commenting, and speed optimization.
Improved simplification, added the fixed problem ("tests/linear.in") to the tests.
Significant changes from Maxima 5.9.1 to 5.9.2, in no particular order.
Magnitude of changes varies widely.
* Parser is now entirely case sensitive, built-in keywords and
variables are all lowercase only
* Regularize case in printed messages

* Enhancements to tensor packages (Atensor, Ctensor, Itensor)
* Replaced Airy functions with much more extensive implementation
* Revisions to Bessel functions
o Bessel functions with real order and complex argument can be
evaluated numerically.
o bessel_j can be computed for negative real order.
* Revisions to gamma function
o Gamma function can be numerically evaluated for complex arguments.
* Revisions to elliptic functions
o Bugs 1165488 and 908185 fixed.
o Fixed issue where many of the routines were returning single-float
results instead of double-float when given rational args.
o elliptic_f with complex args can be numerically evaluated.
o Other inverse Jacobi routines can be evaluated at complex points.
* Extensive revisions to hypergeometric functions
o Adjusted routines to return the new names for the Bessel functions
(like bessel_j instead of %j).
o Similarly, any orthogonal polynomials now use the naming
conventions used by the specfun orthogonal polynomial package.
o Corrected many errors in implementation.
o Some missing internal functionality added.
o Bug 1155241 fixed.
o Bug 1097915 fixed.
o Branch cuts for various relationships between hypergeometric
functions and Legendre functions were implemented or corrected.

** Added an error check to trap multifit calls with fewer observations
than parameters. Previously calling the multifit routines with n<p
would cause invalid memory access.
** Added the Debye unit to physical constants.
** Added cumulative distribution functions for the discrete
distributions, including binomial, poisson, geometric, negative
binomial, pascal and hypergeometric.
** Added the functions gsl_cdf_beta_{Pinv,Qinv} and
gsl_cdf_fdist_{Pinv,Qinv} for computing the inverse of the cumulative
beta and F distributions.
** Added the multilinear fit estimator function gsl_multifit_linear_est
for computing model values and their errors.
** Avoid division by zero in gsl_multimin_fdfminimizer_vector_bfgs
if the step-size becomes too small.
** Users on DEC Alpha systems will need to specify their desired IEEE
arithmetic options via CFLAGS when building the library, as these are
no longer added automatically.
** Added new random variate generators gsl_ran_gaussian_ziggurat
and gsl_ran_gamma_mt for the Gaussian and Gamma distributions based on
the Marsaglia-Tsang ziggurat and fast gamma methods.
** Improved the speed of the exponential power distribution
gsl_ran_exppow.
** Improved the speed of the Gaussian ratio method by adding quadratic
bounds in gsl_ran_gaussian_ratio_method.
