This MATLAB function creates a surface plot of the function z = f(x,y) over the default interval [-5 5] for x and y.
fsurf(f) creates a surface plot of the symbolic expression f(x,y) over the default interval [-5 5] for x and y. example fsurf(f,[min max]) plots f(x,y) over the interval [min max] for x and y. example fsurf(f,[xmin xmax ymin ymax]) plots f(x,y) over the interval ...

本文展示了MATLAB中的surf，surfc，surfl，surfnorm，surface五个绘图命令。它们的具体解释如下：surf--3D shaded surface plot;surfc--Contour plot under a 3D shaded surface plot;surfl--Surface plot with colormap-based lighting;surfnorm--Compute and display 3D surface normals;surface--Creat surface object...
surfc(X,Y,Z) creates a three-dimensional surface plot with a contour plot underneath. A surface plot is a three-dimensional surface that has solid edge colors and solid face colors. The function plots the values in matrix Z as heights above a grid in the x-y plane defined by X and ...
