- 高斯概率模型：
bash
[f,xi] = ksdensity(x): returns a probability density estimate, f, for the sample in the vector x.
The estimate is based on a normal kernel function, and is evaluated at 100 equally spaced points, xi, that cover the range of the data in x.代码：
bash
>> %Give a random sample
x=[2*randn(6000,1); 5+randn(4000,1)];
%Calculate the probability density of each point
[f,xi]=ksdensity(x);
%plot
subplot(211);
plot(x);
title('Sample Data')
subplot(212);
plot(xi,f);
title('PDF');
