* Compatibility with Matlab graphics is much better now. We now
have some graphics features that work like Matlab's Handle
Graphics (tm):
* The way Octave handles search paths has changed.
* Previous versions of Octave had a number of built-in variables to
control warnings (for example, warn_divide_by_zero). These
variables have been replaced by warning identifiers that are used
with the warning function to control the state of warnings.
* All built-in variables have been converted to functions.
* For compatibility with Matlab, the output order of Octave's
"system" function has changed.
* For compatibility with Matlab, the output of Octave's fsolve
function has been changed.
* For compatibility with Matlab, normcdf, norminv, normpdf, and
normrnd have been modified to compute distributions using the
standard deviation instead of the variance.
* For compatibility with Matlab, gamcdf, gaminv, gampdf, gamrnd,
expcdf, expinv, exppdf and exprnd have been modified to compute
the distributions using the standard scale factor rather than
one over the scale factor.
This switches from the release candidate to the real release, changes
are bugfixes and some stylistic changes.
pkgsrc note: the .omf file for the documentation is missing in
the distribution. I've pulled it from CVS. This workaround can
hopefully be removed on the next update.
(The website still refers to 1.6.3 as the current stable version.)
A tentative implementation of Gomory's mixed integer cuts was
included in the branch-and-cut solver. To enable generating
Gomory's cuts the control parameter gmi_cuts passed to the
routine glp_intopt should be set to GLP_ON. This feature is
also available in the solver glpsol through command-line option
'--gomory'. For more details please see the reference manual
included in the distribution.

A tentative implementation of MIR (mixed integer rounding) cuts
was included in the MIP solver. To enable generating MIR cuts
the control parameter mir_cuts passed to the routine glp_intopt
should be set to GLP_ON. This feature is also available in the
stand-alone solver glpsol via command-line option '--mir'. For
more details please see the reference manual included in the
distribution.
The implementation is mainly based on the following two papers:
1. H. Marchand and L. A. Wolsey. Aggregation and mixed integer
rounding to solve MIPs. CORE discussion paper 9839, CORE,
Universite catholique de Louvain, June 1998.
2. G. Andreello, A. Caprara, and M. Fischetti. Embedding cuts
in a Branch&Cut framework. Preliminary draft, October 2003.
MIR cuts can be generated on any level of the search tree that
makes the GLPK MIP solver to be a real branch-and-cut solver.
A bug was fixed in the routine lpx_write_cpxlp. If a variable
x has upper bound and no lower bound, it should appear in the
bounds section as "-inf <= x <= u", not as "x <= u". Thanks to
Enric Rodriguez <erodri@lsi.upc.edu> for the bug report.
Changes since 12.7.7:
10/10/07 - Proper error reporting for shelling out (! command).
10/12/07 - Created directory "m4" to play with using m4 to allow easily
entering functions through macros.
10/14/07 - Improved "set dir" to display the new current directory and to
default to the home directory.
10/17/07 - Entering "=" by itself now swaps equation sides instead of doing
nothing.
10/18/07 - New "mathomatic.ico" file with transparent background.
10/21/07 - Increased speed of taylor command up to 3 times by not doing an
unnecessary simplification.
Added "tests/distance.in".
10/22/07 - Fixed a small problem in calculate command, allowing instant
calculation of (2+2i)^99 now.
Entering any power of any complex number should work now.
10/29/07 - Solving now reports what degree polynomial the equation is.
11/12/07 - Fixed 3 bugs in optimize command.
11/16/07 - Fixed another bug in optimize command.
The following new API routines were added:
glp_read_sol read basic solution from text file
glp_write_sol write basic solution to text file
glp_read_ipt read interior-point solution from text file
glp_write_ipt write interior-point solution to text file
glp_read_mip read MIP solution from text file
glp_write_mip write MIP solution to text file
changes:
-Use Lambert W to solve more equations and avoid infinite loop when solving
some equations
-More data on elements
-Fix simplification of (1-1/x)^3 and similar
-Fix clumsy mistakes in with prefixes leading to crashes
-Fix parsing of unit expressions (when converting) such as W/(m K)
-Add more exact values for sin() and cos() and avoid floating point underflow
by, in approximate mode, checking against the value of pi
-Always input decimal separator sign on keypad separator press
-Fix crash when expression entry reclaims focus if compiled with optimizations
(GTK+)
-New units: typographic units, pouce, pied du roi, grams of TNT and tons of TNT
-New functions: lambertW(), addDays(), addMonths(), addYear(), addTime(),
isNumber(), isReal(), isRational(), isInteger(), representsNumber(),
representsReal(), representsRational(), representsInteger()
-New variable: omega constant
-Other minor fixes and enhancements
also fix wrong inclusion of scrollkeeper/bl3
by any system that pkgsrc supports anyway. It seems to only be used by
ultrix and it isn't clear that scilab still works on ultrix anyway and it almost
certainly doesn't under pkgsrc.
