对信号进行设定层数的小波分解。只输入参数信号、层数及小波类型即可，里面有验证程序。(Decompose the signal with the layer you set.Just input parameter signal, the number of layers and wavelet types.)

利用BLACKMANHARRIS窗口设计一个频率采样型FIR滤波器，对一段含噪音的音乐信号进行滤波去噪处理并根据滤波前后的波形和频谱分析滤波性能。(design a frequency-sampling FIR filter utilizing BLACKMANHARRIS window to filter and de-noise some of the music signal,and analysis filtering performance based on waveform and spectral before and after filtering.)

说明：  Leslie模型实例：基于Leslie矩阵的算法，同时将人口按10年一组分成m个年龄段，并根据一些影响人口数量和结构的重要因素（建立模型。再根据我国近十年的二孩出生率的实际情况并结合少数民族不受影响的因素，通过Matlab画出拟合曲线对2017-2030年我国每年人口总数做出预测。此后，根据近十年0-14岁、15-64 岁、65岁及以上三个年龄段的人数，计算出人口抚养比，用Matlab预测至2030年的人口结构。为了使预测更加精确，我们还将夫妇的生育意愿考虑到模型当中。(Based on the Leslie matrix algorithm, the population is divided into m age groups according to a group of 10 years, and according to some important factors that affect population size and structure Modeling. Then according to the actual situation of the birth rate of second-born children in China in the past ten years and combining the factors that are not affected by ethnic minorities, drawing a fitting curve through Matlab will make a prediction for the total population of China in 2017-2030. After that, based on the number of people aged 0-14, 15-64, and 65 years of age in the last ten years, calculate the dependency ratio of the population and use Matlab to predict the population structure by 2030. In order to make the prediction more accurate, we also consider the couple's fertility intention in the model.)

说明：  脉内线性调频、脉间频率步进信号的模糊函数(Linear FM pulse, pulse frequency step signal ambiguity function)
