这是用matlab软件解决各种一元二次方程(it is use matlab software to solve a unknown equation problems)

如何从CSV、文本文件中读取记录波形 并返回波形数据 逐行读取文件内容 (How CSV, text file read and returns the waveform data recorded waveforms to read file contents line by line)

music algorithm for variation of snr

说明：  本文使用了两种方法优化matlab的程序，缩短了算法的时间。方法1：使用Optimization Toolbox中的并行优化；不需要修改代码。方法2：增加一行代码，即可优化(Improving Optimization Performance with Parallel Computing)

用matlab中的ode45的数值解法解给定初始条件的微分方程组(using matlab command ode45 to numerically solve ODE initial conditions)

music算法界面实现，使用matlab中的gui产生了良好的互动界面(Interface to realize music algorithm, using matlab GUI produced in good interactive interface)

说明：  提取滤波器耦合矩阵:利用特征值和T向量构造M矩阵，并进行相似变换求得不同结构的滤波器耦合矩阵(Extract filter coupling matrix: use eigenvalues and T vectors to construct M matrix, and perform similar transformations to obtain filter coupling matrices with different structures)

使用matlab编写三角形单元的有限元程序( the main code of this files is using matlab to calculate triangle element)

说明：  这里介绍了一种基于自适应滤波的噪声抵消法，采用归一化最小均方误差算法，采集实际噪声环境下各种不同信噪比的带噪语音样本进行降噪处理，实验结果表明，处理后信号的信噪比得到了较大程度的提高，大大改善了听音效果，具有很高的可懂度，且语音自然度好，没有失真；并与谱减法进行了比较，自适应噪声抵消法的降噪幅度比谱减法有一定提高，在听音效果上，用自适应噪声抵消法处理后的语音在清晰度，自然度方面优于谱减法。(Here a novel adaptive noise cancellation method using normalized least mean square algorithm, collecting a variety of actual noise environment, the SNR of noisy speech samples for noise reduction, experimental results show that treatment After the signal to noise ratio was greater improvement in the level, greatly improved the listening results, with high intelligibility and naturalness of speech is good, no distortion and were compared with the spectral subtraction, adaptive noise cancellation law than the spectral subtraction noise reduction rate of a certain improvement in the listening results, and with the adaptive noise cancellation method in the treatment of voice clarity, naturalness is better than spectral subtraction.)

书中通过大量实例，介绍了如何利用遗传算法工具箱函数编写matlab程序，解决实际问题(Through a large number of examples in the book, introduces how to use genetic algorithm toolbox function. Write the matlab program to solve the actual problem )
