Re: [Brahms-dev-l] c++ question

Hi Erik,

You have to make it a pointer to a pointer **, Root has a TMatrix class 
that might be useful....

void Main ()
{
  Float_t SiPhi[6][42];
  LoadPhiMap(SiPhi);
  for (Int_t i = 0; i<6; i++) {
    for (Int_t j = 0; j<42; j++) {cout<<SiPhi[i][j]<<endl;}
  }
}

void LoadPhiMap(Float_t **SiPhi)
{
  
}
