隐马尔科夫模型是语音识别中的重要算法思想，这里在matlab下实现了一个原理性的算法(Hidden markov models is an important algorithm in speech recognition, here under the matlab implements a rational algorithm)

相当详细的matlab程序，使用牛拉法计算电力系统的潮流计算，里面都有注释！很给力！绝对有用！(Fairly detailed matlab program, using bovine Rafah computing power system load flow calculation, which has a comment! Is to force! Absolutely useful!)

VERY IMPORTANT MATLAB BROGRAM FOR FRFT

说明：  程序描述了电压为-0.377V的情况下，卡尔曼滤波器的输出。其中“+”为观测值。程序注解写的很清楚很容易看懂。(Procedure describes the voltage of-0.377V, the Kalman filter output. Which+ For the observed values. Notes written procedure is easy to understand very clearly.)

介绍了自适应均衡方面的一些文章和代码，可供有需要的同志参考实用。(Describes some aspects of adaptive equalization articles and code, there is a need for practical reference comrades.)

分数傅里叶计算一维时间序列，非常实用，可以得到时间序列频谱(Computation of the Fractional Fourier Transform)

说明：  page变换例程，可以对信号进行柯恩类时频分布中的page变换(page conversion routines, you can type on the signal time-frequency distribution of Cohen)
