Hi everyone,
   I have three lists like
            x = [x1,x2,x3, ......xn]
            y = [y1,y2,y3, ......yn]
            z = [z1,z2,z3, ..... zn]
   How can I contour z against x, y plane?
   Since I know nothing about Matlab. Based on the contour_demo.py, I still don't know how to contour my  three list x, y, z.
    Thanks for your help.
