说明：  《MATLAB在电子信息课程中的应用》中的第五章的习题源程序( MATLAB curriculum in electronic information applications in Chapter V source Exercises)

该程序使用小波包变换分析信号的特征向量和各频率成分的功率谱.(The program uses the wavelet packet analysis of the signal eigenvectors and the frequency components of the power spectrum.)

this code helps you to calculate the autospcter (autospecter_code)

这是matlab简易教程，对初学者有帮助(This is a matlab easy tutorial for beginners)

小波去噪的阈值去噪发法，在图像方面很有用(Wavelet denoising threshold denoising hair method is useful in image areas)

FFT源代码，该源代码比较全面，稍微改动即可使用，欢迎下载，谢谢！(FFT source code, the source code is more comprehensive, you can use a little change, welcome to download, thank you!)

解相干的MUSIC算法，用于阵列信号处理(Decorrelation MUSIC algorithm for array signal processing)

henon吸引子方法用于混沌 时间序列的分析，懂得可以拿来参考一下下(Henon attractor method is used to chaotic time series analysis, can be used to reference this week )

模糊综合评判方法即将评价目标看成是由多种因素组成的模糊集合（称为因素集u），再设定这些因素所能选取的评审等级，组成评语的模糊集合（称为评判集v），分别求出各单一因素对各个评审等级的归属程度（称为模糊矩阵），然后根据各个因素在评价目标中的权重分配，通过计算（称为模糊矩阵合成），求出评价的定量解值。它是应用模糊变换原理和最大隶属度原则，对各因素作综合评价的。(The fuzzy comprehensive evaluation method is about evaluation goal as a fuzzy set by a variety of factors (called factor set u) set the assessment level of these factors can be selected to form the fuzzy set of reviews (called evaluation set v) were calculated the level of the individual assessment of each single factor attribution the quantitative solution value (called a fuzzy matrix), then the weight distribution according to various factors in the evaluation objectives, by calculating (called fuzzy matrix synthesis), obtained evaluation . It is the application of fuzzy transform principle and the principle of maximum degree of membership for a comprehensive evaluation of various factors.)

共轭MUSIC与平滑MUSIC，来实现波达方向估计(The conjugated MUSIC smoothing MUSIC DOA estimation)
