Mathworks File Exchange频道近期更新了一个小函数。能够将三维数据矩阵相应的函数u=f(x,y,z)可视化的显示出来。
对我们这些常和数据分析问题打交道的人爱说。还是有点參考价值的.....把它放到这里,供大家參考

2.函数的语法格式:
function h=view3d(data,exponent,maxsize,linewidth)
3.各个參数的说明
% data: Input data(3 dimensional)
% exponent: Exponential scaling factor for values( greater than 1)
% maxsize: Maximum point size
% linewidth: Edge thickness of points
%
4.调用实例
clc;clear all;close all;
[x,y,z]=meshgrid(-1:0.25:1,-1:0.25:1,-1:0.25:1);
t=exp(1-x.^2)+exp(1-y.^2)+exp(z.^2);
view3d(t,1.4);
5.可视化效果
6.The end! Enjoy your happy moring!
