TMinuit

Hi all,
I am trying to minimize a multidimensional function and I am having problems in 'composing' the function. The TF3, and TFormula classes allow me to write expressions but I have to explicitly set the limits of each variable (min,max). The problem is that my variable values are unevenly spaced in each dimension. The values in each dimension is actually the x,y,z cartesian coordinate values representing locations in space. Is there a way to explicitly pass on the variable values and not just use the minimum and maximum values.
