Hi again and thanks for the support
My question is simple, how i can to draw a vector field of the gradient of a
z=f(x,y) function???
i mean, the gradient of z is:
∇Z=(∂z/∂x) î + (∂z/∂y) ĵ
so i want to graph the vector field as seen on pages 9 and 23 on this PDF:
http://www.math.msu.edu/~hensh/latex/pstricks/seminarSS08.pdf<http://www.math.msu.edu/%7Ehensh/latex/pstricks/seminarSS08.pdf>
i think that i could use simply a "double multido" for x and y and graph the
vectors, but i dont know how to get the color effect shown in the PDF...
thanks for the support again
