My matrix is 15x15.
I want to call this ROOT function from c++.
Which Root function?Please be more specific.

Hi,
Have a look at
const TMatrixD EigenVectors(TVectorD& eigenValues) const or
const TMatrix EigenVectors(TVector & eigenValues) const :
TMatrixD a(15,15);
.
.
TVectorD eigenVal;
const TMatrixD eigenVec = a.EigenVectors(eigenVal);
At the moment vector a has to be symmetric !
