	  features in a testsuite for tcltest 1.0. Rewritten the tests
	  using this custom comparison command to be tcltest 1.0
	  compliant.

	* pkgIndex.tcl: With permission from Arjen moved math::statistics
	* bessel.test: into the 8.4 section. Due to its new dependency on
	* elliptic.test: math::linearalgebra via multi-variate linear

	  as well.

2007-08-20  Andreas Kupries  <andreask@activestate.com>

	* bessel.test: Added missing dependency on math::linearalgebra.

                    (contribution by Eric Kemp-Benedict)
	* statistics.tcl : sources "mvlinreg.tcl" now
	* mvlinreg.tcl   : original source code from Eric, still needs some polishing
                    (the test case needs to be integrated too)

2006-11-06  Arjen Markus  <arjenmarkus@users.sourceforge.net>

	* fuzzy.test : fixed a dependency on Tcl 8.4 behaviour in one test case

        * bigfloat.tcl : when a number is close to zero,
        * bigfloat.test  it takes the precision into account,
        * bigfloat2.tcl  so instead of getting '0' we get '0.e-4'.
        * bigfloat2.test [math::bigfloat::iszero] is not impacted

	  information for math::bignum.

2006-02-21  Arjen Markus  <arjenmarkus@users.sourceforge.net>

	* linalg.tcl (matmul): Fixed [SF Tcllib Bug xxxxxxx]. 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  <arjenmarkus@users.sourceforge.net>

	* bignum.tcl (rshift): Fixed [SF Tcllib Bug 1098051]. (Solution

2005-11-04  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * roman.test: removed extraneous messages

2005-10-26  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * qcomplex.tcl: error in the computation of the complex
                        cosine. Found by Oscar Andreas Lopez.

2005-10-21  Andreas Kupries <andreask@activestate.com>

	* interpolate.test: Reduced requirement for struct down to
	* interpolate.tcl:  struct::matrix, as that is the only structure
	  used by this package. This means that we are loading 272 KB less

	  after having done much benchmarks

2005-09-06  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.tcl : new and faster algorithm to compute Pi

2005-08-31  Stephane Arnold <sarnold75@users.sourceforge.net>

	* bigfloat.tcl : added many comments and fixed some minor bugs

        * Fixed bug #1272910: due to the different rounding
          of 0.5 in Tcl 8.5, the Quantiles-1.0 test failed.
          Using different levels steers the test away from
          this odd edge case.

2005-08-29  Stephane Arnold <sarnold75@users.sourceforge.net>

	  began with '+' ; another bug, in [fromdouble], when
	  a number began with '+' or '-'.
	* bigfloat.test : Added tests for fromdouble.

2005-08-04  Andreas Kupries  <andreas_kupries@users.sourceforge.net>

	* bigfloat.man: Replaced a number of ?...? occurences to markup

2005-08-01  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * Changed the credits for Ed Hume at his request
          (anti-spam measure)

2005-07-26  Stephane Arnold

	* Changed in many places : '[pi $precision]'
	  to '[pi $precision 1]' in which $precision is treated
	  as binary digit length (instead of decimals)
	  since the internal representation of the mantissa is binary

2005-03-16  Andreas Kupries <andreask@activestate.com>

	* bigfloat.tcl: Added package require math::bignum. If we use the
	  package we should load it as well.

	* rational_funcs.tcl: Redone entry '2004-11-22 Andreas Kupries
	  <andreask@activestate.com>'. Somehow the source command came
	  back.

2005-03-11  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Corrected problem with exponential_Ei - doubly defined

2005-01-14  Arjen Markus <arjenmarkus@users.sourceforge.net>

          (newer versions will come later on)

2005-01-10  Andreas Kupries <andreask@activestate.com>

	* bignum.tcl:  Integrated [Tcllib SF Bug 1093414]. Basic bit
	* bignum.test: operations (and, or, xor) on big numbers. Correct
	* bignum.man:  operation is limited to positive numbers (including
	  zero). The basic code was provided by Aamer Aakther
	  <aakther@users.sourceforge.net>, modifications of docs, and
	  small testsuite by myself.

2005-01-05  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Added tests for matmul (and corrected the implementation)

2005-01-04  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Expanded the documentation (it should now describe all
          public procedures)
        * Expanded the tests (not complete, but it should cover most
          more complicated procedures)
        * Expanded the set of procedures (only a few algorithms
          await implementation)

2005-01-03  Arjen Markus <arjenmarkus@users.sourceforge.net>

        * Added modified Gram-Schmidt method to the linear algebra package

	* rational_funcs.tcl: Removed bad source'ing of file
	  polynomials.tcl. Depended on current working directory in the
	  right place, and superfluous as well, as immediately after a
	  'package require' of the package loaded it in the proper
	  manner. Disabled the test code at the end as well.

2004-11-08  Arjen Markus  <arjenmarkus@users.sourceforge.net>

        * Added preliminary versions of a linear algebra module
          (revision of Hume's LA). No documentation yet

	  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  <andreask@activestate.com>

	* fuzzy.test: Re-applied bug fixes I did before (See 2003-04-13)
