Lasso变量选择方法创始人的经典代码，内含多个源代码，每个可单独运行(Lasso variable selection method, founder of the classical code, containing more than one source code can be run separately for each)

1.用matlab实现心形图的绘制，用极坐标的形式或用隐函数的形式实现， 2.玫瑰形的matlab实现(1. Using matlab mapping to achieve heart-shaped, with polar coordinates in the form or the form of implicit function implementation, 2. Rose-shaped matlab implementation)

说明：  这是国外一本经典教材附带的程序，通信系统的matlab实现，所含例子丰富(This is a classic foreign materials attached to the procedures, communications systems to achieve matlab contains abundant examples of)

这是一个三次样条插值的.m程序 输入的是一个二维数组A(Nx2) 插值方法为: S(x) = A(J) + B(J)*( x - x(J) ) + C(J)*( x - x(J) )**2 +D(J) * ( x - x(J) )**3 for x(J) <= x < x(J + 1) (This is a cubic spline interpolation. M program input is a two-dimensional array A (Nx2) interpolation method: S (x) = A (J)+ B (J)* (x- x (J ))+ C (J)* (x- x (J))** 2+ D (J)* (x- x (J))** 3 for x (J) )

利用偏最小二乘法实现对近红外光谱的血液定量分析(Quantitative analysis of blood in near infrared spectrum by partial least squares)

基于自组织神经网络的矢量量化编码Ｍatlab程序(Based on self-organizing neural network vector quantization coding Matlab procedures)

2D math algorithm library to manipulate 2D vectors and matrix

<<现代信号处理教程>>(胡广书版)书中配套的matlab源代码。(this is a matlab code of the book called modem signal processing.)

利用MATLAB GUI设计实现图像处理的图形用户界面，利用MATLAB图像处理工具箱 实现以下的图像处理功能。 1、 采用matlab Guide设计图像界面与按钮界面。 2、 连接摄像头，编写MATLAB初始化程序。 3、 用摄像头采集一幅图像，并能实现保存（使用控件按钮保存）。 4、 设计按钮实现对图像进行任意的亮度和对比度变化调节，显示和对比度变化前 后的图像 5、设计按钮实现用户能够用鼠标选取图像感兴趣区域，显示和保存该选择区域。 (Image processing using MATLAB GUI design graphical user interface, using the MATLAB image processing toolbox Implement the following image processing functions. 1, Guide design based on matlab image with the button interface. 2, connect camera, write MATLAB initialization. 3, use camera to collect an image, which can be saved using the control button to save). 4, design button implementation for any changes in brightness and contrast adjustment, display and contrast changes before After the image of the 5, design interest to be able to use the mouse to the image button to achieve the user area, display and save the selected area. )

说明：  采用10阵元的阵元间距为1/2波长的均匀线阵，估计两个不相干的信号源的波达方向。假设信号 源分别来自 和 方向，信噪比分别为10dB和20dB；并假设样本数为100。使用music算法实现DOA估计(music algorithm used for doa estimation)
