2012-09-06  Joe Boudreau <boudreau@cern.ch>

	* DiagMatrix, GenMatrix, SymMatrix: add invert() and inverse() methods
	  Added two methods to [-,Diag,Sym]Matrix to carry out the matrix 
	  inversion without the users needing to provide an ierr flag. 
	  These methods are all inline and called invert() and inverse(), 
	  so they overload the existing inversion routines for the relevant class.  
	  If an error occurs, then an std::runtime_error is thrown.

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.

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

	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"

	  Implementation of invertHaywood4()

	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.

	* 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>>

	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.
