Is it possible to set "error matrix" to gMinuit?

Hi,

I’ve enjoyed drawing 2D contour by gMinuit->Contour…

Is it possible to set “error matrix” and set the central (x,y) to gMinuit so that I can ask ROOT to gMinuit->Contour(…) for me ??

Hi,

Can you please elaborate more on your question ? I am not sure I have understood what you would like to do,
