非常著名的曲线拟合程序

1999-05-04  Federico Mena Quintero  <[e-mail]>

	* src/util/DataConverter.cpp: #include <errno.h>

1998-12-14  Asger Alstrup Nielsen  <alstrup@alstrup>

	* src/StringSet.h: New file.  The beginning of a StringSet.

	* src/GooseSet.h: The design is expanded to cover the array operations
	as well, such that AsciiImport can be implemented.

	* src/Value.h: The design evolves.
	* src/DataType.h: The design evolves.

	* src/DataSet.h: Adapted to GooseSet. It still remains to be renamed 
	to RealSet as discussed.

	* src/ColumnDivider.h: Small clean-ups.

	* src/AsciiImport.cpp: Adapted to DataType/Value system.

	* src/Access.h: new file.  Provides accessors to the polymorphic
	Values.

	* win32/README: Updated appropriately.

	* goose.dsp: Added target for examples in win32 project file.

	* examples/boot_bench.cpp: Fixed examples to compile under win32.

1998-11-29  Asger Alstrup Nielsen  <alstrup@alstrup>

	* src/constants.h: Changed #defines to constants.

	* src/MetaCurve.cpp: Fixes to make goose work on Visual C.
	In general, don't mix #include <iostream.h> and #include<iostream>
	include styles.  We *only* use the latter ones.  A few other fixes
	to make things work on Win32.

	* win32/config.h: Hand-made config.h file for the Win32 platform.

	* goose.dsp: Updated. We compile cleanly with Visual C.

	* win32/README: New file with brief info about the Win32 port.

	* src/AsciiImport.cpp: New structure:  The template stuff has been
	pushed out to two helper classes: AsciiReader and WarningController.
	This trims the AsciiImport.h file a lot, and hopefully helps on the
	compilation problems we've had.

	* src/AsciiReader.h: New file.  This is an interface to a  
	ascii format reader used by the ascii import engine.  We provide a 
	generic caching reader, CachingAsciiReader.

	* src/WarningController.h: New file.  This is an interface to a simple
	warning reporting facility.  This was pulled out of the big ascii
	import class to make things more modular.

	* examples/test_ascii_import.cpp: Updated to new structure.

1998-11-24  Asger Alstrup Nielsen  <alstrup@alstrup>

	* src/stringtools.h: bug fixes, and a few new functions.

	* src/Value.h: new file. This implements a proposal for values in the
	new type system proposal.

	* src/DataType.h: Implemented proposal for new type system.

	* src/DataSet.cpp: Reverted some of the changes required to get the
	stuff compiling under MS Visual C++.  I discovered that Visual C++
	can be set up to understand the for-scoping rules correctly.
	Everything still compiles cleanly by Visual C++ v5 and v6.

	* src/ColumnDivider.h: new file. This implements the splitting of the
	input file into columns.  Taken from from AsciiImport.cpp/h and
	expanded.  See also src/ColumnDivider.cpp.

	* src/AsciiImport.h: Implemented more of the auto-setup stuff.

	* examples/test_ascii_import.cpp: Now this test program can import
	ascii files without any explicit set-up information.  Unfortunately,
	egcs-2.90.29 (release v1.0.3) can only compile it with all optimizations
	turned off.

1998-11-06  Asger Alstrup Nielsen  <alstrup@alstrup>

	* src/stringtools.cpp: new file with some useful string routines.
	* src/stringtools.h: new file.

	* src/AsciiImport.cpp: new file with column divider implementations.

	* src/AsciiImport.h: Implemented parts of autosetup.

1998-11-05  Asger Alstrup Nielsen  <alstrup@alstrup>

	* test/basic.txt: new file.  Simple test-file for the ascii import
	facility.

	* doc/ascii_import.txt: new file. White-paper that describes the
	ascii import facility specs.

	* examples/test_ascii_import.cpp (main): new file.  This one tests
	the AsciiImport class.  At the moment, it provides all set-up 
	parameters by itself, but this should not be needed later.

	* src/AsciiImport.h: New file.  This implements the Ascii Import
	facility.  I haven't tested everything yet, and I haven't implemented
	the automatic setup-stuff yet, but the framework is there.

1998-10-28  Asger Alstrup Nielsen  <alstrup@alstrup>

	* src/statfn.cpp: Provided implementations of erf() and erfc() for
	Win32.  They were taken from the cephes public domain library.  Also,
	the normal distribution was changed a bit according to the way it
	was done in cephes.  It should be a little more precise now.

	* src/StatsDB.cpp: Changed the form of initialization to make it
	understandable even to the VC++ compiler.

	* src/Random.cpp: A few "#if defined WIN32"s to get it going. Windows
	does not have support for getpid() and "/dev/random".  So now, the
	random seed is only initialized with time().  Hopefully, I'll figure
	out a way to get more entropy on this platform later.

	* src/DataSet.cpp: Got rid of a bunch of assert()s, and changed to
	Exception's instead.  Unfortunately, I also had to rename a bunch
	of index-variables, because the stupid VC++ compiler does not conform
	to the C++ for-scoping standard.  I really hate this change, but
	unfortunately, this is life.

	* src/Exception.h: Removed the bunch of different exception classes.
	I have chosen to just use the Exception class instead, because it was
	difficult to decide which of the others to use.  Also, I reformatted
	all thrown messages to hopefully look good when displayed in a GUI.

	* src/DataImport.h: Changed #includes from <algo.h> to <algorithm>,
	and <iostream.h> to <iostream>.  This should conform to STL better.
	Also, when we need less<> and greater<>, we should include 
	<functional>.  Finally a "using namespace std;" has been added in
 	order to comply with the C++ standard.
	These kind of changes have been done in other files as well.

	* goose.dsp: New Microsoft Developer Studio v6.0 project file.
	This is just set up to compile the library for now.  Later I'll
	get the DLL going.

	* examples/test_statsdb.cpp: Renamed from statsdb.cpp because
	Windows filesystem is not case sensitive, and thus the Microsoft
	compiler was confusing this with StatsDB.cpp in src/.

	* .cvsignore: Simplified a bit.  In doc/, we have to keep changes
	to Makefile.am, because that one is not autogenerated.
