- new version (v. 13) of TUnfold from S. Schmitt
The big change is from including another class "TUnfoldSys"
This class provides support for the propagation of systematic errors.

from Stefan Schmitt: new version (v12) of TUnfold
TUnfold is sensitive to yet another bug in the TMatrixSparse class
(bug report #45807).
The multiplication bug is already handled in TUnfold version 11, but the bug with adding two matrices is only fixed in this new version 12
There are some other changes, like improved error handling for those cases where the matrix may get singular and thus the unfolding could give completely wrong results.

new version of TUnfold from S. Schmitt.
Changes in detail:
Changes to the TUnfold class from v6 to v11
===========================================
tutorials/math/testUnfold1.C
tutorials/math/testUnfold2.C
----------------------------
* print-out of both chi**2 contributions and the number of degrees of freedom
hist/hist/inc/TUnfold.h
-----------------------
new or changed functionality:
* new members
fNDf
GetNdf()
GetNpar()
* return codes [error count] rather than excessive printout for
RegularizeSize()
RegularizeDerivative()
RegularizeCurvature()
RegularizeBins()
RegularizeBins2D()
* additional argument and return code
SetInput()
matrix operation:
* remove method CreateSparseMatrix and use TMatrixDSparse::SetMatrixArray()
instead
* add methods for matrix operations, replacing corresponding calls to
TMatrixD or TMatrixDSparse methods for any of the following reasons
(a) better performance (multiple matrix operations required when using
TMatrixDSparse or TMatrixD)
MultiplyMSparseTranspMSparse()
MultiplyMSparseM()
MultiplyMSparseMSparse()
MultiplyVecMSparseVec()
(b) work-around for a bug in TMatrixDSparse (bug #45415)
MultiplyMSparseTranspMSparse()
MultiplyMSparseM()
MultiplyMSparseMSparse()
MultiplyVecMSparseVec()
(c) improved performance for matrices with a certain structure
InvertMSparse()
hist/hist/inc/TUnfold.cxx
-------------------------
changes to existing methods
Double_t TUnfold::DoUnfold(void)
* use internal matrix manipulation methods
* try to avoid TMatrixDSparse::operator+=(TMatrixDSparse const &)
because it creates a memory leak (bug #45502)
void TUnfold::CalculateChi2Rho(void)
* use internal matrix manipulation methods
TUnfold::TUnfold(TH2 const *hist_A, EHistMap histmap, ERegMode regmode)
* reduce the amount of printout for rejected bins
* use TMatrixDSparse::SetMatrixArray()
instead of TUnfold::CreateSparseMatrix()
Int_t TUnfold::RegularizeSize()
Int_t TUnfold::RegularizeDerivative()
Int_t TUnfold::RegularizeCurvature()
* return the number of errors rather than doing a lot of printout
Int_t TUnfold::RegularizeBins()
Int_t TUnfold::RegularizeBins2D()
* return the number of errors
Int_t TUnfold::SetInput()
* third argument for user specific treatment of bins with zero error.
By default, bins with zero error are now skipped
(old version: the error was set to 1)
* return value: the number of bins which have zero error
Int_t TUnfold::ScanLcurve()
* the outermost points of the L-curve may have ill-defined curvature,
so they are now excluded from the scan
TH1D *TUnfold::GetOutput()
TH2D *TUnfold::GetRhoIJ()
TH2D *TUnfold::GetEmatrix()
* remove some dead code
TH1D *TUnfold::GetInput()
* use internal matrix manipulation methods
TUnfold::GetLcurveX()
* bug fix in the definition of chi**2
new methods
TUnfold::MultiplyVecMSparseVec()
TUnfold::MultiplyMSparseMSparse()
TUnfold::MultiplyMSparseTranspMSparse()
TUnfold::MultiplyMSparseM()
TUnfold::InvertMSparse()
TUnfold::GetNdf(void)
TUnfold::GetNpar(void)
removed methods
TUnfold::CreateSparseMatrix()
