Function to plot ellipse in matlab

Generate a random sample of size n a finite mixture estimate of the Old Faithful Geyser data

把输入的十进制小数，转换为二进制。输入的十进制区分正负数(no description)

anc 算法的反馈实现，在国外的论文中的算法的simulink实现(anc used the feedback,and realize it used the simulink)

This estimator correctly identifies the two distinct directions of arrival.

能够把输入信号分解为多个IMF分量，并进行Hilbert变换，求得信号的时频分布谱图。(Be able to input signal is decomposed into several IMF components and carry out Hilbert transform, time-frequency distribution obtained spectrum.)

说明：  通带截止频率 =1000Hz，阻带截止频率 =1200Hz，采样频率fs=5000Hz，通带衰减系数 =0.3dB，阻带衰减系数 =40dB。(The digital filter are the digital signal processing important content, the digital filter may divide into IIR and the FIR two main kinds. As for the IIR digital filter design, we need the help of analog prototype filter, and then transform analog filter into digital filter. )

说明：  详细给出floyd、dijkstra算法，并给出具体例子以及如何看运行结果。所有程序均通过真实测试。(Details are given floyd, dijkstra algorithm, and gives specific examples and how to look at the results. Through all the procedures are the real test.)

采用了小波去噪的思想，独立成分分析算法降低原始数据噪声，一个师兄的毕设。( Using wavelet denoising thought, Independent component analysis algorithm reduces the raw data noise, A complete set of brothers.)
