This program generates an approximating polynomial by the least squares technique to a set of points (x,y,z) where z = f{x,y). The data, which need not be equally spaced, may be weighted or not at the option of theuser. The program allows for any number of points. The number of powers of x and y may be increased by altering the dimension statement.
