The Fourth Dimension Space

枯叶北风寒，忽然年以残，念往昔，语默心酸。二十光阴无一物，韶光贱，寐难安； 不畏形影单，道途阻且慢，哪曲折，如渡飞湍。斩浪劈波酬壮志，同把酒，共言欢！ -如梦令

2-dimensional gauss function with Matlab (使用Matlab绘制二维高斯函数图象)

by using following codes.
%%
X1 = [0:0.1:10];
X2 = [0:0.1:10];
[X,Y] = meshgrid(X1,X2);
Z = exp(-((X-5).*(X-5)+(Y-5).*(Y-5))/18);
surf(X,Y,Z);
%%
the result is as following...



2D gauss function.
and the distribution of 4*(x*y)/pow((x+y),2) is
X1 = [0:1:100];
X2 = [0:1:100];
[X,Y] = meshgrid(X1,X2);
Z = 4*X.*Y./(X+Y)./(X+Y);
surf(X,Y,Z);
the relationship between eigenvalues of Harris Matrix

so we can see along the line y=x the value is maximized.

没有本质联系 只是我想验证一下那个函数而已。。。  回复  更多评论
