matlab code to calculate active leve of speech

说明：  fiir和iir滤波器设计源码，交流交流，希望给人帮助！(fiir source and IIR filter design, communication exchange, hoping to give people help!)

本文为Stephen J.Chapman《MATLAB 编程（第二版）》英文影印版的中文译本，这本 书对初学者很好的入门教材。(This article Stephen J.Chapman " MATLAB Programming (second edition)," The Chinese translation of the English version of a photocopy, this book is a good primer for beginners.)

omp 算法 你可以通过这个算法完成图像恢复，效果好，恢复时间短，误码率低，解决凸优化算法复杂度高的缺点(omp algorithm you can accomplish by this algorithm for image restoration, good effect, shorter recovery time, error rate, to solve the shortcomings of convex optimization algorithm with high complexity)

this test checks the value of Number.

说明：  自适应滤波器相关的matlab程序，包含LMS，RLS算法等的实现。由于太大了，所以该资源分为part1和part2两部分。此部分为part2！(matlab codes related to adaptive filters, including LMS and RLS algorithm, etc. the resource is divided to two parts (part1 + part2) cuz it is oversized.)

基於matlab編寫LDPC之編碼及BF、SPA、Log-SPA等演算法及系統錯誤率計算(The preparation of LDPC codes based on matlab and BF, SPA, Log-SPA and other algorithms and system error rate)

双容水箱的液位控制问题。首先对被控对象的模型进行分析，并采用实验建模法求取模型的传递函数。其次，设计PID控制器，在Matlab/Simulink环境下建立双容水箱控制的仿真模型，对PID控制算法进行仿真研究。通过仿真实验，证明该设计方法可行性和该算法的正确性。最后完成了基于PLC的双容水箱液位控制的软硬件设计，编写了PLC梯形图实现了水箱液位的PID控制。(Dual tank water level control problems. First, the controlled object model for analysis and modeling approach using experimental strike transfer function model. Secondly, the design of PID controller, simulation model dual tank water control in Matlab/Simulink environment, PID control algorithm simulation. Simulation results show that the design feasibility and correctness of the algorithm. Finally completed the hardware and software design of PLC-based dual-tank water level control, the preparation of the PLC ladder to achieve the tank level PID control.)
