边缘是指图像中像素灰度有阶跃变化或屋顶状变化的那些像素的集合。学会并掌握使用matlab进行图像的边缘检测，设计用户界面实现上述功能。 实际问题： 1、采用matlab Guide设计图像界面，可以读入并显示图像，设计实现以下功能的菜单，点击相应的菜单（如radio button）在图像界面上可以显示相应的功能。 2 使用sobel检测算子； 3 使用prewitt检测算子； 4 使用canny检测算子； (Edge is refers to the image pixel has a step change in the collection of those pixels or roof shape change. Learn and master using matlab for image edge detection, design the user interface to realize the function. The real problem: 1, Guide design based on matlab image interface, can be read and displayed image, design and implement the following function menu, click on the corresponding menu (such as a radio button) in the image on the interface can display the corresponding function. 2 use the sobel detection operator 3 use prewitt detection operator 4 use the canny detection operator )

实现脉冲压缩与相控阵的matlab实现 脉冲压缩雷达发射宽脉冲信号，接收和处理回波后输出窄脉冲的雷达。为获得脉冲压缩的效果，发射的宽脉冲采取编码形式，并在接收机中经过匹配滤波器的处理。脉冲压缩雷达的优点是能获得大的作用距离和具有很高的距离分辨力。(pulse compression&phased array)

noisegen.m：生成白噪声并按照指定信噪比对语音进行加噪； add_noisem.m：使用输入的噪音按照指定信噪比对语音进加噪； SNR_singlech.m：输入纯净语音和加噪后的语音，计算其信噪比； my_add_noise.m：调用上述函数进行加噪操作；(noisegen.m: white noise generated by the specified signal to noise ratio of the speech plus noise add_noisem.m: use the specified input noise into the signal to noise ratio of the speech plus noise SNR_singlech.m: pure voice input and processing after the noise voice, calculate the signal to noise ratio my_add_noise.m: call the above functions plus noise operation )

径向基函数插值使用一系列基函数，它们在每个采样点对称且居中。径向基函数是一类特殊的函数，其主要特征是它们的响应与中心点的距离单调地减小（或增加）。中心、距离刻度和精确的形状是模型的参数。(Radial Basis Function interpolation with biharmonic, multiquadric, inverse multiquadric, thin plate spline, and Gaussian basis functions for Matlab/Octave. RBF interpolation uses a series of basis functions that are symmetric and centered at each sampling point. Radial basis functions are a special class of functions with their main feature being that their response decreases (or increases) monotonically with distance from a central point. The center, the distance scale, and the precise shape are parameters of the model.)
