spech Lpc pitch detection

说明：  本程序由matlab编写，通过求解光纤激光器的速率方程，给出激光功率分布(This program prepared by matlab, the rate of fiber lasers by solving the equation for the distribution of laser power)

matlab画圆形，然后四周涂成其他颜色--换言之，可以画出口面场的分布情形，非常形象逼真(matlab draw round, and then painted the other colors around- in other words, can draw the distribution of farm export side, a very vivid)

FFT Filters provide precisely controlled low- and high-pass filtering (smoothing and sharpening, respectively) using a Butterworth characteristic. The image is converted into spatial frequencies using a Fast Fourier Transform, the appropriate filter is applied, and the image is converted back using an inverse FFT

matlab code for enegy detector

说明：  基于最小二乘的Matlab拟合算例 相当好用(Based on the Matlab least squares to be quite cost-effective use cases)

利用克拉茂克郎尼变换， 求得表面等离子体相位实数部分与入射光角度或波长的关系(Estimation of the real via Kramers-Kronig relations)

小数据量法求Lyapunov指数_龙格库塔(Small amount of data Lyapunov index _ method Runge-Kutta)

OFDM仿真代码，对理论值与实际值做了相应对比。 (OFDM simulation code, to the theoretical value to do with the actual value of the corresponding contrast.)

matlab中一些实用函数的集合，是初学者很好的学习辅助工具(matlab collection of some useful function, is a very good learning tool for beginners)
