IIR

这是一个matlab编写的计算人脸识别率的小程序，选选用的图像数据库位ORL数据库。，已通过测试。 (This is a matlab write a small program to calculate the face recognition rate, the election chosen image databases bit ORL database. , Has been tested.)

用k2算法从先验概率构建贝叶斯网络，实现推理，结构学习，参数学习用贝叶斯方法。(K2 algorithm using Bayesian network built from the a priori probability to achieve reasoning, structure learning, parameter learning.)

可以对数量少、残缺、不完整的数据进行预测，如人口、缺水量等。也可以对灾害发生时间进行预测。(Can be a small number, mutilated, incomplete data to predict, such as population, water shortage and so on. You can also predict the time of occurrence of the disaster.)

本代码是PID在S函数中的实现，但不同之处在于，本代码先把PID变成状态空间表达式，更加易懂，为本人独创。(This code is the PID in the S function, but the difference is that, this code to put the PID into the state space expressions, more understandable, for my original.)
