matlab
从初值出发,先计算y对时间t的导数,得到y的变化速度;求出x对t的导数,得到x随时间的变化速度。然后时间前进一小步h=0.002,同时x和y也都发生一个小的变化,即在原来数值基础上加上时间步长h和变化速度的乘积。如果x到达1或者-1,强制让y发生变化。这个过程不断迭代,得到结果。

mcmc
MCMC方法主要是为了解决有些baysian推断中参数期望E(f(v)|D)不能直接计算得到的问题的。
其中v是要估计的参数,D是数据观察值(The concept consists of two parts:markov chain and monte carlo integration。)
