行程编码的matlab实现。编码后的图像存储在变量E中,该变量是一个三纬树组,前两纬表示起始像素的横、纵坐标，第三纬表示该行程的颜色值。,Matlab coding realize itinerary. Encoded image is stored in the variable E, the variable is a three-wai Tree Group, the former two-wai express start pixel horizontal, vertical coord

MATLAB函数，绘图函数，在同一平面用来绘制三个不同纵坐标图。-MATLAB function, mapping function, in the same plane used to draw three different vertical plot.

用此程序可以画三维图，以经纬线为横纵坐标，以价格为z轴建立三维图。(With this program, you can draw a three-dimensional map, the latitude and longitude line for horizontal and vertical coordinates, the price for the Z axis to create three-dimensional map.)
