Worked more on the comments in the matrix package  . Actually the
important
ones are all there .. but have to add thing slike "cop constructor" to
make the checker happy .

Added also namespaces TMatrixTCramer and TMatrixTSymCramerInv to the
dictionary

"I have implemented all copy and equal operators needed to silence all
warnings in AliRoot, as requested. I have implemented shallow copies as
would do the default operators synthetized by the compiler.
Most operators are protected. If users complain, you just have to move
them into the public area, but class derivation is of course supported.
It has been a terrible job, I have modified 278 files, but the changes
are backward compabile, and this goes a long way to permitting user to
use the effc++ flag with root headers."

In order to remove a temporary TMatrixD object in TMatrixTSym::Invert,
an incorrect dynamic_cast was performed . This caused (luckily) a crash
in stressLinear .
The temporary object has been inserted again .

The result was memcpy-ed back to the original matrix despite the

Assert   ->  R__ASSERT
Check    ->  R__CHECK
Change the TCollection.h macro:
ForEach  ->  R__FOR_EACH
This to avoid potential problems due too trivial macro names.
The old macros will be removed in the next release. Currently
they will print out warning messages with the advice to move
to the new macro names.

- 2 weeks ago AMultB.. functions were made public . However, unlike any
other
   public function except for the *= calls, it could allocate an object
. In addition
   already Mult function existed (which called AMultB with constr=0) .
   This situation is rectified in the following way :
     The public Mult, MultT and TMult are introduced .

     AMultB , AtMultB and AMultBt are now functions that do not belong
to the
     TMatrixT class anymore, they accept now pointers as arguments .

     None of these functions will create a new object . In internal
calls to AMultB family ,
     first a call to Allocate is made (if necessary) .

    AMultB is used in one of the TMatrixTSym::Similarity calls,
removing the creation of a
    TMatrixT object .

- smatrix/test function reflect the changes above

1) TVectorT TMatrixT TMatrixTSym TMatrixTSparse : made sure that
IsValid Assert's
    are only done when gMatrixCheck is kTRUE
2) TMatrixTSym::Similarity and SimilarityT create a temporary matrix .
If storage
     is <= kWorkMax use a local array . This way less temporary
elements are
    created .
3) In  TMatrixTSym::Similarity and SimilarityT some shape checking was
missing

  void Add(const TVectorT<Element> &v);
  void Add(const TVectorT<Element> &v1, const TVectorT<Element> &v2);
The first function  adds vector v to this.
The second function adds the 2 vectors v1 and v2 and store the result into this.

a modification for TMatrixTSym::Invert :

Replaced the Bunch-Kaufman decomposition in the TMatrixTSym::Invert
by LU decomposition because it is signifivantly faster .
However, Bunch-Kaufman guarantees unlike LU that the inverted matrix
is symmetric . In case of numerically difficult matrices, the user
should use the TDecompBK class to invert.

Warning:  This means that some file that relied on the indirect
inclusion of these header file might now fail to compile with
an error message mention that gROOT is no known or that TClass,
TROOT or TStreamerInfo is incompletely defined.  Simply add the
proper include directive.

Dictionary G__%.o: G__%.cxx rules now in main Makefile instead of Module.mk's
=> changes in Module.mk.

First Module.mk's included, then Makefile.precomp - we need ALLHDRS defined

Split $(PCHEXTRAOBJ) and $(PCHFILE) rules - fixes clash with make -j2

Define CINTCXXFLAGS:= - otherwise they will contain PCHCXXFLAGS via
their definition as a copy of CXXFLAGS.

MSVC: prevent LNK4206 linker warning (-Yl...)

Fix a bug in the TMatrixDRow / Column / Diag when
trying to manipulate a row / column / diag with one of another

a patch that will hopefully resolve the Solaris issue .

From the error messages I deduce that the compiler does not like to
instantiate
a default templated argument in the function header . Therefore, I
replaced the default
value by the value 0.0 (which is an unusual value , the user would use
here "==")
and check in the routine and replace it with the appropriate epsilon.

1) As pointed out by Philippe, LinkDef.h contained two functions with
the wrong
    signature , resulting in CINT problems as seen in running the
tutorial solveLinear.C

2) A few enum declarations for internal usage haved been moved from
public to protected

1) Added to LinkDef.h the NormalEqn function from TDecompChol . They
got
    lost in this file during the transition to the templated version of
the matrix library .

2) Replaced in the templated code everywhere references to DB_EPSILON
and DBL_MIN
    by the templated version through <numeric_limits> .
