Hi, In relation to a research problem, I have three arrays/vectors X,Y,Z of dimension 3000 X 1 each. I need to find a list of numerical values for dz/dx or dz/dy. I could not find any command for numerical differentiation using forward, backward or central diference formulas. Then I need to plot contours of those differential values. How do I do this? I am pretty much new in handling Mathematica. Thanks, Sreeparna
