The bug concerns the possibility of using row vectors. Because I did not think they were possible/practical, I regarded all vectors as column vectors or row vectors whenever suitable. Row vectors are however practical, so I needed to add these cases, at least for [matmul]. 2006-02-13 Arjen Markus * bignum.tcl (rshift): Fixed [SF Tcllib Bug 1098051].

Corrected inconsistent * interpolate.tcl: package version number in interpolate.tcl. * interpolate.test: * qcomplex.test: * optimize.man: Added min_bound_1d and min_unbound_1d functions * optimize.tcl: to do one-dimensional function minimization, * optimize.test: constrained and unconstrained, respectively, without derivatives. 2004-06-16 Andreas Kupries * interpolate.man: Added a missing list_end before section examples. Fixed usage of braces in the example as well. 2004-06-16 Arjen Markus * added the modules complexnumbers, special, interpolate, constants 2004-05-23 Andreas Kupries * * Released and tagged Tcllib 1.6.1 ======================== * 2004-02-15 Andreas Kupries * * Released and tagged Tcllib 1.6 ======================== * 2004-02-09 Jeff Hobbs * combinatorics.tcl (::math::factorial): correct fac 171 off-by-one and use of -strict in string is int|double. 2003-12-22 Joe English * calculus.man (rungeKuttaStep): Add missing argument in function synopsis (bug report from Richard Body). 2003-10-29 Arjen Markus * statistics.tcl (BasicStat): Applied fix for [SF Tcllib Bug 820807]. Uniform data may cause a small negative value when computing the base value for a standard deviation, instead of the correct 0.0. The fix now enforces 0.0 when encountering this situation. This entry in the ChangeLog by Andreas Kupries. 2003-05-05 Andreas Kupries * * Released and tagged Tcllib 1.4 ======================== * 2003-04-24 Andreas Kupries * pkgIndex.tcl: Found math::optimize missing in index. * optimize.man: Version number inconsistent with code, corrected. * calculus.test: Converted [puts] into log statements, and suppress them by default. Reduces the noise when running the testsuite. * math.test: Added output listing the version of the * statistics.test: package we are testing. * calculus.test: * geometry.test: * combinatorics.test: * optimize.test: 2003-04-24 Arjen Markus * liststat.tcl: Corrected the handling of the expression in the list manipulation procedures. This solves the scope problem (bug 725231). AK: Lifted from the 'cvs log'. This passes the testsuite. 2003-04-23 Andreas Kupries * fuzzy.test: Re-applied bug fixes I did before (See 2003-04-13) to the newly committed version, which was not merged, but simply overwrote my changes. 2003-04-21 Andreas Kupries * optimize.test: Corrected errors in loading the functionality under test, and of accessing tcltest. Now functional. 2003-04-18 Joe English * pkgIndex.tcl: Added math::statistics after yesterday's commit by Arjen Markus. * statistics.test: Changed to conform to standard of importing tcltest, changed import of tested functionality, added checks that actually tcltest 1.2 or higher is used (Aborting if not). * statistics.tcl: * liststat.tcl * pdf_stat.tcl: * plotstat.tcl: Reformatted a bit to be more near to the style-guide with regard to indentation. 2003-04-13 Andreas Kupries * pkgIndex.tcl: * fuzzy.tcl: Committed new code (see #535216), this also updates the package to version 0.2 * fuzzy.man: * fuzzy.test: New files for fuzzy comparisons, documentation and testsuite. Fixed some bugs in them. NOTE: There are failures in the testsuite. 2003-04-11 Andreas Kupries * combinatorics.man: * math.man: * math.tcl: * pkgIndex.tcl: Set version of the package to to 1.2.2. 2003-01-16 Andreas Kupries * combinatorics.man: More semantic markup, less visual one. * calculus.man: 2002-06-03 Andreas Kupries * pkgIndex.tcl: updated calculus to version 0.5. * calculus.man: Added [require] declarations. * calculus.README: * calculus.CHANGES: * calculus.tcl: * calculus.test: * calculus.man: Applied changes for #553773 on behalf of Arjen Markus . 2002-05-08 Don Porter * calculus.test: Corrected testing problems by namespace-ifying the file. 2002-04-15 Andreas Kupries * combinatorics.man: Added doctools manpage. * math.man: Added doctools manpage. 2002-03-25 Andreas Kupries * calculus.man: Fixed formatting errors in the doctools manpage. 2002-02-15 Andreas Kupries * Update of calculus. #528434 * calculus.man: New file, calculus documentation in doctools format. * calculus.test: New file, beginnings of testsuite * calculus.CHANGES: * calculus.README: * calculus.tcl: * pkgIndex.tcl: updated to calculus 0.3 2002-02-14 Andreas Kupries * combinatorics.tcl * geometry.tcl (proc): Frink run * math::geometry: Version is now 1.0.1 to distinguish this from the code in tcllib release 1.2 * math: Version is now 1.2.1 to distinguish this from the code in tcllib release 1.2 2002-01-18 Don Porter * math.tcl: [namespace export Beta] got out of sync with the command name. * misc.tcl: removed [package provide math]; duplicated in math.tcl, a sync problem waiting to happen. 2002-01-18 Andreas Kupries * Bumped version to 1.2. 2002-01-18 Andreas Kupries * Added calculus functionality and fuzzy FP comparison as provided by Arjen Markus as is. This code currently has neither true testsuite nor good documentation but was considered important enough to get in now. Polish has to come in the subsequent patch releases. 2002-01-11 Kevin Kenny * combinatorics.tcl: Removed incorrect 'package provide'. 2002-01-11 Kevin Kenny * math.tcl: * misc.tcl: * pkgIndex.tcl: * tclIndex: Reorganized so that math.tcl is a top-level 'package provide' script and loads a tclIndex. The code from 'math.tcl' moves into 'misc.tcl'. * combinatorics.n: * combinatorics.tcl: * combinatorics.test: Added a 'combinatorics' module containing the Gamma function and several related functions (factorial, binomial coefficient, and Beta). (Feature request #484850). 2001-06-21 Andreas Kupries * math.tcl: Fixed dubious code reported by frink. 2000-10-06 Eric Melski * math.test: * math.n: * math.tcl: Added ::math::fibonacci function, to compute numbers in the Fibonacci sequence. 2000-09-08 Eric Melski * math.test: * math.n: * math.tcl: Added ::math::random function. * pkgIndex.tcl: Bumped version number to 1.1. 2000-06-15 Eric Melski * math.n: * math.test: * math.tcl: Incorporated sigma, cov, stats, integrate functions (from Philip Ehrens ). [RFE: 5060] 2000-03-27 Eric Melski * math.n: * math.test: * math.tcl: Added sum, mean, and product functions (from Philip Ehrens ). 2000-03-09 Eric Melski * math.test: Adapted tests for use in/out of tcllib test framework. 2000-03-07 Eric Melski * pkgIndex.tcl: * math.tcl: * math.test: * math.n: Initial versions of files for math library.
