Interpolation v2.0 by Ruben Rostamian. SPLINE generates a piecewise cubic and twice continuously differentiable interpolation y(x) of a set of points (x_i,y_i), i=1,2,...,n. It is assumed throughout that x_1 < x_2 < ... < x_n.

3D Surface Graphing Program by David D Jansen. Some features are: 1. It doesn't go belly up if it encounters a divide by zero or undefined result. 2. It allows the domains of the XY plane to be defined to any value ( although it centers the plot on the origin). 3. The equation is entered in X, Y, Z format not parametric form. 4. It creates a matrix of the topology of the surface which is useful for locating actual values of a max or min.
