It might be that the Matrix dll must be loaded explicitely:
gSystem->Load("Matrix") (check name in $ROOTSYS\lib).

Since Matrix is not used internally in ROOT it does not get
included by the "clever" Windows linker (although it appears
on the link line).

Cheers, Fons.

PS: the used TVector ctor exists:

//______________________________________________________________________________
TVector::TVector(Int_t lwb, Int_t upb, Double_t va_(iv1), ...)
{
// Make a vector and assign initial values. Argument list should contain
// Double_t values to assign to vector elements. The list must be
// terminated by the string "END". Example:
// TVector foo(1,3,0.0,1.0,1.5,"END");
