edgedetect

matlab采集的 噪声源码，有多个资源可供分析，是做音频噪声研究的理想材料(Acquisition noise matlab source, there are several resources available for analysis, so the audio is an ideal material for the noise study)

说明：  matlab 绘制极坐标图 绘制直角坐标图(matlab matlab matlab matlab)

record program to record sound in matlab

一级单摆的模拟与仿真，采用的matlab语言编写的，是一个二阶的非线性系统！(Modeling and simulation of a pendulum, the matlab language, is a second-order nonlinear system!)

Implementation of brute force algorithm of pattern recognition.

对图像进行方向滤波,可以消除图像中有规律的网格或者直线干扰(direction filter)

基于逻辑回归的多分类问题，可以实现至少三类数据的分类(Classification based on multiple logistic regression, classification can be achieved at least three types of data)

说明：  用matlab读取雷达基数据，并计算相关仰角等(Using MATLAB to read the radar base data and calculate the relative elevation)

利用周期图法对序列的功率谱进行估计。数据窗采用汉明窗。假设在白噪声中分辨这三个不同频率的正弦信号,其相位是均匀分布在2PI的独立随机变量,而 是一个单位白噪声.生成50个长度为N=512的 的样本序列集合。 (use map cycle sequencing method of the power spectrum estimation. Data window using Hamming window. Assume that the white noise to differentiate between the three different frequency sinusoidal signal, its phase is uniformly distributed in the PI two independent random variables. but a flat white noise. Generating 50 length N = 512 samples of the sequence set.)
