Need 2-dimensional Y versus X curve fit routine [message #9506]

CURVEFIT in the IDL built-in library which performs a nonlinear fit of a 1-D data vector Y to a function of a 1-D vector X and a parameter vector A. I am looking for a routine similar except that Y and X are two dimensional (time versus depth). CURVEFIT is based on Bevington's CURVFIT (Marquardt's method). I extended a fortran CURVFIT routine to 2-D some years ago, but hate to repeat the effort in IDL. Has anybody got a 2-D version?

I've already checked the searchable IDL library website with no luck.

Thanks for the help.
