Dear gurus,
I am using the following function to get interpolation points in a 3D surface. I am doing it for the sake of finding the intersection line between two surfaces:

   gsl_spline_eval(spline, x, acc);

Unfortunately, the abave line failed to work when the data 'x' is a constant, since it is from a flat surface. I understand that x has to be in ascending order, but I hope to find a quick fix when x is a constant... Thanks for your valuable advices.
