Tue Jun 10 09:18:46 2008 Jiri (George) Lebl <jirka@5z.com> * Release 1.0.3 Sat Jun 07 13:02:21 2008 Jiri (George) Lebl <jirka@5z.com> * src/matop.c, src/funclib.c, src/eval.c: Add a new flag to not do backsubstitution in gauss if we are interested in nullspace and the matrix is nonsingular * src/matop.c: fix the return value of gauss. Singular means nonempty nullspace, i.e. maximal row rank. This also fixes SolveLinearSystem which didn't work according to specs, i.e. it is supposed to return null when solution is nonunique. * src/geniustests.txt: add more tests Thu Jun 05 11:40:58 2008 Jiri (George) Lebl <jirka@5z.com> * src/funclib.c: fix argument checking in MillerRabin. Also zeros, ones, rand, randint, I, SetMatrixSize now accept 0 for size and return null as an empty matrix. Also wait, IndexComplement accept 0 and work accordingly. * help/C/gel-function-list.gel: update accordingly Wed Jun 04 11:56:25 2008 Jiri (George) Lebl <jirka@5z.com> * help/C/genius.xml, help/C/gel-function-list.gel: update the docs a little, fix a few typos, add links. Wed Jun 04 03:51:25 2008 Jiri (George) Lebl <jirka@5z.com> * src/gnome-genius.c: figure out a way to work around VTE nonsense, one way to get at current absolute row is by checking the cursor location and assuming it is on the last line. Improve monitoring by using a text buffer and allow to turn off the automatic updates. Full answer is now wrapped if not a matrix. Don't set icon if it doesn't exist to avoid warning. Don't try to use readline helper from current dir if not in dev dir. Tue Jun 03 20:14:34 2008 Jiri (George) Lebl <jirka@5z.com> * src/gnome-genius.c: fix some capitalization issues, implement a variable monitor dialog. Also add code to save current console but that is disabled due to VTE having useless (read: unusable) API for getting at the buffer. You require some private knowledge to use the get_text_range function. Otherwise the API is pointless. Thu May 22 01:10:40 2008 Jiri (George) Lebl <jirka@5z.com> * src/funclib.c: fix identity matrix caching, setup type caches for identity, zeros and ones * src/matop.c: move rref caching to gauss to speed up inverting matrices in rref form etc... Tue May 20 02:36:47 2008 Jiri (George) Lebl <jirka@5z.com> * lib/number_theory/primes.gel: update slightly the upper bound on double checked mersenne prime exponents to newest value Tue May 20 00:25:10 2008 Jiri (George) Lebl <jirka@5z.com> * src/matrixw.[ch], matop.c, src/eval.c, src/funclib.c: Optimize matrix manipulation a bit. Don't be overly conservative with making things private. And OMG we used Gauss-Jordan instead of backaddition. Also when the matrix is not rational, do pivotting (use largest entry, not first nonzero one) * src/mpwrap.c: fix mpw_abs if called with same arguments for in and out and add mpw_abs_sq for getting the absolute value squared, which doesn't involve a sqrt * src/genius.c, src/gnome-genius.c, src/eval.[ch], src/matrixw.c: init the_zero during the startup * src/mpzextra.c: very minor optimizations * src/Makefile.am: fix BUILDDIR setup Mon May 19 19:56:37 2008 Jiri (George) Lebl <jirka@5z.com> * src/mpzextra.c: fix leak on mympz_is_prime. Sun Feb 24 18:38:31 2008 Jiri (George) Lebl <jirka@5z.com> * help/C/genius.xml: update Sun Feb 24 18:35:45 2008 Jiri (George) Lebl <jirka@5z.com> * src/calc.c: print extra dict of a function by printing a list of variable assignments before the function body. * src/dict.c: a little cleanup and fix the problem with subst list updating and d_replacefunc which happened when a local variable which was previously set to something else was set to a function. * src/geniustests.txt: add more tests on returning functions and the subst list handling * help/C/genius.xml: add section on returning functions from functions Sun Feb 24 15:25:45 2008 Jiri (George) Lebl <jirka@5z.com> * src/dict.c, src/funclib.c: Add IsDefined and undefine. Implement d_delete. protect and unprotect now work with matrices of identifiers. * src/geniustests.txt: add tests * help/C/*.xml: update docs * TODO: problems with subst lists can lead to crash, document this Fri Feb 22 02:44:23 2008 Jiri (George) Lebl <jirka@5z.com> * src/calc.c, src/mpwrap.c: avoid warning Fri Feb 22 02:41:35 2008 Jiri (George) Lebl <jirka@5z.com> * src/*.[ch]: update copyright string as appropriate Fri Feb 22 02:11:03 2008 Jiri (George) Lebl <jirka@5z.com> * configure.in: raise version * lib/number_theory/primes.gel: Add IsMersennePrime and MersennePrimeExponents * help/C/gel-function-list.xml, help/C/genius.xml: document the above Fri Feb 22 01:38:54 2008 Jiri (George) Lebl <jirka@5z.com> * src/mpwrap.[ch]: add mpw_re_sgn and mpw_im_sgn functions and fix memory leak in mpw_re and mpw_im * src/funclib.c: Implement QuadraticFormula internally, marginally improving performance, but mainly handle special cases better and avoid instability in solutions (avoid bad cancellation in most cases) * lib/equation_solving/formulas.gel: remove QuadraticFormula from here * src/longtest.gel: add tests for quadratic formula Sat Jan 12 15:03:19 2008 Jiri (George) Lebl <jirka@5z.com> * src/eval.c: make internal function calling a bit faster. Can be noticeable (tested 10% on fast operations) * src/funclib.c: fix memory leak Thu Nov 29 10:34:41 2007 Jiri (George) Lebl <jirka@5z.com> * help/C/gel-function-list.gel, lib/combinatorics/misc.gel: Fix spelling of the Fibonacci function name.
