Two Dimensional Surface Fitting Program 1.0

This program represents a further development of the standard powerful d-deDUnlinfitd-deDt facility already in matlab. The major problem with d-deDUnlinfitd-deDt is that it can only handle fitting of one dimensional arrays (x, y) where x is the independent variable and y is the dependent one.The program fit2 uses another program d-deDUfitfitd-deDt where the user fitting function can be defined. This user defined function is defined in line 6 of fitfit as ff in terms of a,x,y.The input arguments to the program are 1- a which is an array representing the starting values of the free fitting parameters ( similar to that when nlinfit is used) The length of a must be equal to the number of parameters used in the user defined function to be fitted (line 6 in the M-file "fitfit" 2- x and y are each a one dimensional array representing the independent variables 3- z is the dependent variable matrix whose elements are functions of the meshgrid values of x and y please read the pdf file for more information and example
