Summary of important user-visible changes for fuzzy-logic-toolkit 0.6.2:
------------------------------------------------------------------------
** Redefined the defuzz option "centroid" using a more efficient method
(weighted average), and renamed the previous "centroid" implementation
"centroid_integral" (because it is an integral-based calculation) in
order to continue to provide the integral-based option. Most previously
written code using the old "centroid" definition will continue to work
without alteration, but in case of error, replace DefuzzMethod='centroid'
with DefuzzMethod='centroid_integral' in the .fis file. For an example,
see investment_portfolio.fis and investment_portfolio_demo.m.
Summary of important user-visible changes for fuzzy-logic-toolkit 0.6.1:
------------------------------------------------------------------------
** Improved many comments and updated the html documentation.
Summary of important user-visible changes for fuzzy-logic-toolkit 0.6.0:
------------------------------------------------------------------------
** Added many built-in self tests, simplified error messages, and
made minor improvements to comments.
** Reimplemented two private functions: square_distance_matrix.m
and update_cluster_membership.m. Tested for identical results
with previous implementation using an embedded test in each file.
** Added new docs directory containing html documentation for each
top-level function.
Summary of important user-visible changes for fuzzy-logic-toolkit 0.5.1:
------------------------------------------------------------------------
** Updated several top-level text files (ChangeLog, DESCRIPTION, and
NEWS). No change to any code.
Summary of important user-visible changes for fuzzy-logic-toolkit 0.5.0:
------------------------------------------------------------------------
** Replaced several occurrences of the deprecated '.+' and '.-'
operators with '+' and '-', respectively.
Summary of important user-visible changes for fuzzy-logic-toolkit 0.4.6:
------------------------------------------------------------------------
** Bug #53549 was fixed (parse error in function defuzz.m --
anonymous function body requires only a single expression).
Summary of important user-visible changes for fuzzy-logic-toolkit 0.4.5:
------------------------------------------------------------------------
** Bug #38018 was fixed (typo in function setfis.m -- wrong function name).
Summary of important user-visible changes for fuzzy-logic-toolkit 0.4.4:
------------------------------------------------------------------------
** The function readfis was modified to workaround the change to
strsplit beginning in Octave 3.8.0. Without the modification,
readfis will not work with Octave versions >= 3.8.0. The new
version of readfis works with all versions of Octave >= 3.2.4
by first checking for the version number of Octave and then
selecting either ostrsplit (for Octave >= 3.8.0) or strsplit
(for Octave < 3.8.0).
** The files writefis.m and evalmf.m were edited to maintain
compatibility with future versions of Octave. Two occurrences of
the continuation "..." within double quoted strings in writefis.m
were changed to "\". One occurrence of "..." in evalmf.m was
removed by writing the instruction on a single line.
Summary of important user-visible changes for fuzzy-logic-toolkit 0.4.2:
------------------------------------------------------------------------
** The demos embedded in partition_coeff.m, partition_entropy.m,
and xie_beni_index.m were merged with the embedded demos in
fcm.m and gustafson_kessel.m.
Summary of important user-visible changes for fuzzy-logic-toolkit 0.4.1:
------------------------------------------------------------------------
** The package is no longer automatically loaded.
** The following demo scripts were rewritten and embedded in fcm.m,
gustafson_kessel.m, partition_coeff.m, partition_entropy.m, and
xie_beni_index.m:
fcm_demo_1
fcm_demo_2
gustafson_kessel_demo_1
gustafson_kessel_demo_2
(The separate demo script files have been removed.)
Summary of important user-visible changes for fuzzy-logic-toolkit 0.4.0:
------------------------------------------------------------------------
** The following functions are new:
fcm
gustafson_kessel
partition_coeff
partition_entropy
xie_beni_index
** The following demo scripts are new:
fcm_demo_1
fcm_demo_2
gustafson_kessel_demo_1
gustafson_kessel_demo_2
