Changes since 2.0.13: (besides numerous bug fixes)
- New math functions: besselh, airy
- New functions: is_complex, isnumeric, isfinite, rehash, graw
- The Bessel functions now accept complex values for the argument
and any real value for the order.
- New "finance" category
- ~30 new functions in "signal"
- Numerous new functions in "statistics" category, including
new "distributions", "models", and "tests" directories
- If LOADPATH contains a doubled colon, the default path is inserted
in its place. This is similar to the substitution that also takes
place for leading or trailing colons in the LOADPATH.
- Loops of the form `for i = STRING ... endfor' are now allowed.
... and much more.
Closes PR8421.
since it contains loadable shared object files that are platform-specific.
Lots of bug-fixes and additions ... it's getting closer to a usable
replacement for S-PLUS.
* added a directory colorcode with code to htmlize the scripts. it also color-highlights
the code. Try it out by typing './colorcode' in that directory, and then
'netscape scriptsmain.html'
* Pattern matching code optimized a little.
* SylvesterMatrix, code supplied by James Gilbertson.
* MatrixRow, MatrixColumn, and GenMatrix supplied by James Gilbertson.
* changed Intersection and Difference, so they handle lists with multiple identical
elements correctly.
* Fixed the D(x)x+y bug reported by Fred Bacon.
* Fixed the Gcd(x,x) bug reported by Scott.
* added Factorize({list}). Factorize(1 .. 4) should now return the same as 4! for instance.
* Added Content and PrimitivePart to the univariate polynomial code. See the manual for an
explanation of these functions.
Yacas (Yet Another Computer Algebra System) is a small and highly flexible
computer algebra language. The syntax uses a infix-operator grammar
parser. The distribution contains a small library of mathematical functions,
but its real strength is in the language in which you can easily write your
own symbolic manipulation algorithms. It supports arbitrary precision
arithmetic.
The current version is 1.0.28 (the first release was 1.0.0). The language is
very much in a finished state. Any code written for it should be usable in
future versions. Also, the language should prove very easy to learn.
Yacas is written in very clean c++ code, and is very portable . It can compile
stand-alone, and is easily embeddable. Yacas contains a native arbitrary
precision arithmetic module, but can also be used with GMP.
Things implemented include: arbitrary precision, rational numeric, vector,
complex, and matrix computations (including inverses and determinants and
solving matrix equations), derivatives, solving, Taylor series, numerical
solving (Newtons method), and a lot more non-mathematical algorithms. The
language natively supports variables and user-defined functions. There is
basic support for polynomials.
Changes are:
* Fix annoying flashing cursor bug.
* Improve inter{sheet,book} references.
* Undo.
* Row/Col hiding.
* Keep cursor visible, Add Alt-Pg{Up,down}
* Clipboard, Selection, & border fixes.
* Revamp the memory handling of the parser.
* Fixed goal seek's behaviour on cancel and failure.
* Bogotised PRODUCT and introduced G_PRODUCT.
* Implemented the auto-format feature.
* Found xml io font size loading bug.
* Excel export clean.
* Python plugin update: Allow calling Gnumeric builtins from
Python.
* Re-wrote dependency engine; lots more speed.
* Improvements on VALUE_BOOL management on the guile plugin.
* Bug fixes.
* Implemented `AutoSave' tool.
* Started `AutoCorrect' tool.
* Some minor improvements to the Solver tool.
* Sorting undo/redo
Gnumeric 0.47
* Fix nasty recalc bug that would hang the app.
* Improve bounding box calculation for printing.
* Improve empty cell loading.
* Re-enable pasting from X.
* Adjust semantics of paste to work even when selection is not
visible.
* Fix import plugins.
Version 0.3.0 changes since 0.2.3:
Bugs fixed:
* Using alphanumeric variables in functions under AGGREGATE
segfaulted. Fixed.
* Under certain circumstances, the final case would be omitted
from the results of an AGGREGATE operation. Fixed.
* Undefined behavior was invoked by referencing a freed pointer
under certain circumstances. Fixed.
* A wrong record size was displayed when paging the active file to
disk. Fixed.
* Not having enough temporary space for sorting caused a core
dump. Fixed.
* Syntax errors in function descriptions on AGGREGATE caused core
dumps. Fixed.
* A null pointer was dereferenced, causing a core dump, when
PERCENTILES was specified on FREQUENCIES. This fixes the
problem, but PSPP still doesn't calculate percentiles.
* SORT always sorted in ascending order. Fixed.
* Some minor memory leaks in the expression parser were removed.
* Many assertions fixed for strict ANSI C compliance.
New features:
* SET ECHO ON now implemented, but turned off by default.
* PRINT specifier supported on END REPEAT.
Other:
* System libgmp2 library is used if installed instead of
unconditionally using the included libgmp2 subset.
* Extensive code cleanup, which continues.
* Added CORRELATIONS command parser, but not implemented.
