Digital-signal-processing

说明：  此程序用于去除信号中的噪声，并且它是基于小波变换的代码，很实用的(This program is used to remove signal noise, and it is based on the wavelet transform code, very useful)

基于active-set 的SQP算法，用于求解非线性不等约束(SQP algorithm used to find a constrained minimum of a function of several variables based on active-set algorithm, subject to the nonlinear inequalities.)

换能器导纳图绘制函数，需要自备换能器导纳数据，代入即可(Transducer admittance mapping function, you need to bring their own transducer admittance data can be substituted into)

利用MATALB进行制冷循环的热力学计算。(Thermodynamic calculation of refrigeration cycle.)

假设检验例题 7.1 设总体 ，其中参数 ， 为未知，试指出下面统计假设中哪些是简单假设，哪些是复合假设： （1） ； （2） ； （3） ； （4） ； （5） . 解：（1）是简单假设，其余位复合假设 (Hypothesis testing for Example 7.1 overall, including parameters, is unknown, pointed out that the following statistical hypothesis test which is a simple assumption, which is a compound hypothesis: (1) (2) (3) (4) (5). Solution : (1) is a simple assumption, the remaining bit composite hypothesis)

说明：  MATLAB中的混沌系统的分析方法，包括李雅普诺夫指数等等(MATLAB in the analysis of chaotic systems, including Lyapunov exponents, etc.)
