2008-07-16  Lynn Garren <garren@fnal.gov>

	* src/SymMatrix.cc, Matrix.cc, DiagMatrix.cc, MatrixLinear.cc: 
	Iterators were set to a nonexistent memory location in many places.
	Even though the iterators were not used, this operation is not allowed 
	and causes problems with the newer VC++ compilers.  
	In some cases, a more efficient rewrite was possible.

==============================
Wed Jun 22 2005  Andreas Pfeiffer  <andreas.pfeiffer@cern.ch>

	* configure.in: changed soname to install_name for darwin targets,
	dylibs still don't build properly on 10.3/10.4, static libs ok.

2005-06-19  Lynn Garren <garren@fnal.gov>

	* configure.in, Makefile.am: 
	Use lib when building Visual C++ libraries.
	Disable shared library build for Solaris CC.

22.04.05 Release CLHEP-2.0.2.0
==============================
2005-04-07  Lynn Garren <garren@fnal.gov>

	* configure.in: set AR and ARFLAGS

2005-03-23  Mark Fischler  <mf@fnal.gov>

	* SymMatrix.cc, testBug7328.cc

	Repair bug introduced into determinant of large matrices, and exposed
	by testBug7328 when it is run on VC++ 7.1.
	Also clean up the test program to avoid declaring loop indices
	in the for loop statement when indices of the same name will be used
	later -- VC++ still fouls up when this is done, though it is proper 
	C++.

2005-03-15  Mark Fischler  <mf@fnal.gov>

	* SymMatrix.cc, testBug7328.cc
	
	Repair of bug 7328, a memory leak encountered when inverting symmetric
	matrices above the size of 6x6.
	
2005-02-25  Mark Fischler  <mf@fnal.gov>

	* Matrix.cc, testBug6181.cc

	size of 6x6.  

2005-02-18  Lynn Garren  <garren@fnal.gov>

	* configure.in, Makefile.am: Stop using libtool.  
	The newer releases of libtool seem to have dropped support for 
	Windows Visual C++.  

2005-02-14  Lynn Garren  <garren@fnal.gov>

	* configure.in: Visual C++ flags are now "-EHsc -nologo -GR -GX -MD"

2005-02-14  Mark Fischler  <mf@fnal.gov>

	* SymMatrixInvert.cc
	
	  Implementation of invertHaywood4()

2005-02-03  Lynn Garren  <garren@fnal.gov>

	* configure.in: install step creates libCLHEP.a, libCLHEP.so,
	and/or libCLHEP.dylib by adding a symbolic link.

2005-02-02  Andreas PFEIFFER  <andreas.pfeiffer@cern.ch>

	* configure.in: modified compiler flags for windows:
	added "-O -GR -GX -MD" as this is needed for the multi-thread
	environments used.

2005-02-01  Lynn Garren  <garren@fnal.gov>

	* Matrix: remove HEP_CC_NEED_SUB_WITHOUT_CONST ifdefs
	HEP_CC_NEED_SUB_WITHOUT_CONST has been defined to 1 in all 
	cases for a long time.

2005-01-31  Andreas PFEIFFER  <andreas.pfeiffer@cern.ch>

	* src/Matrix.h: fixed error in sub(int, int, int, int), savannah 
	bug id 6176, added corresponding files (testBug6176*) in test/,
	updated Makefile.am accordingly to generate tests.

Tue Aug 27 10:11:14 2002 Mark Fischler <mf@fnal.gov>

	* Matrix/Matrix.cc:

	Fix a BUG that was in trace from time immemorial!

	Trace used to return the sum of the elements in the first column,
	rather than the sum of the diagonal elements.

	Warning:  This repair may change the behavior of some programs.
	I claim in those cases, the change is a correction.

Mon Aug 13 11:21:31 2001 Evgueni Tcherniaev <Evgueni.Tcherniaev@cern.ch>

	* Matrix/GenMatrix.cc:

	Added #include <string.h> to provide declaration of memset().

	* Matrix/Matrix.cc:

	All "return invertHaywood...(ierr);" statements have been
	subdivided in two lines: 
	   invertHaywood...(ierr);
	   return;
	to avoid problems on DEC/cxx.

	* Matrix/DiagMatrix.h,SymMatrix.h,Vector.h:

	Removed "explicit" for constructors with two parameters to avoid
	problems on HP/aCC.

	* Geometry/BasicVector3D.h: Corrected operator>>
	
Mon Jul 30 18:31:38 2001 Evgueni Tcherniaev <Evgueni.Tcherniaev@cern.ch>

Mon Jul 30 11:19:43 2001 Mark Fischler <mf@fnal.gov>

	* Matrix/MatrixInvert.cc,SymMatrixInvert.cc (Added):

	These files contain invertHaywood 4, 5, and 6
	and invertChoelsky 4, 5, 6.
	
Fri Jul 27 2001 Mark Fischler <mf@fnal.gov>

	* Matrix/SymMatrix.h,SymMatrix.cc,Matrix.h,Matrix.cc:
	* Matrix/SymMatrixInvert.cc,MatrixINvert.cc (Added):

	Implemented speed-improved inversion for 4x4, 5x5 and 6x6 matrices.
	Inserted the Haywood-style implemtation of inversion for 4x4, 5x5,
	and 6x6 matrices. The speed increase is consdierable for some cases,
	and a bit less in others. In particular, 5x5 symmetric positive
	definite matrices go quite fast now, and these are importat for
	tracking.

	* Matrix/GenMatrix.cc,GenMatrix.icc:

	Zero the elements in the case of pre-allocated storage.
	When constructing a matrix small enough to use pre-allocated array,
	still zero the array data. Lack of this was causing CDF code to crash.

	* Matrix/Vector.h,Matrix.h:

	Made ctor from int explicit.
