说明：  Matlab program for eye detection.

说明：  电压对有功灵敏度计算公式，原理为以潮流计算方程为基础，对潮流方程进行线性化，并且交换顺序(The calculation formula of the voltage to the active sensitivity is based on the power flow calculation equation, the power flow equation is linearized, and the exchange sequence)

语音信号的基音抽出分析，可用于语音识别，效果不错(Pitch out of the speech signal can be used for speech recognition, good results)

last time when i came here to find some clock references. but most of them can not works well. so this files works well on FPGA board.(last time when i came here to find some clock references. but most of them can not works well. so this works well on files FPGA board.)

假设有一组海底深度测量数据，采用插值方式绘制海底形状图。 (High dimensional function interpolation )

多井过程中的井筒计算，以及注采过程中的相关参数(Multi-well process wellbore calculations, and injection process parameters)

根据齿轮基本参数，计算啮合刚度，得到具体的刚度值。(According to the basic parameters of the gear, the meshing stiffness can be calculated.)

使用下面的参数设计信道均衡器，其中使用两个独立的随机数发生器，一个用x(n)来表示，用来测试信道；另一个用v(n)来表示，用来模拟接收器中的加性白噪声的影响。序列x(n)是x(n)=±1的伯努利序列，随机变量x(n)具有零均值和单位方差。第二个序列v(n)具有零均值，其方差由信噪比决定。均衡器有11个抽头。(Use the following parameter design of channel equalizer, which uses two separate random number generator, one with x (n) to indicate, to test the channel the other with v (n) to indicate to simulate the receiver in The additive white noise. Sequence x (n) is x (n) = ± 1 of the Bernoulli sequence of random variable x (n) with zero mean and unit variance. The second sequence v (n) has zero mean, its variance decision by the signal to noise ratio. There are 11-tap equalizer.)
