Flood fill, also called seed fill, is an algorithm that determines the area connected to a given node in a multi-dimensional array. implementation in matlab

超声回波声场数据处理显示（matlab 源程序）(ultrasound )

通过matlab实现最大类间方差,根据迭代选择阈值法原理编写.(Through matlab maximum between-class variance, according to the iterative threshold selection method works written.)

卡尔曼滤波用simulink实现，有3个例子，能运行！(Kalman filter using simulink, there are three examples can run!)

主要是针对面向对象设计中的模块应用，详细见英文说明。。。(NCMGUI Master GUI for Numerical Computing with MATLAB. NCMGUI provides an interface to nineteen of the graphical demostrations from "Numerical Computing with MATLAB". Click on any graphic to access the underlying function.)

本书基于MATLAB 5.2版，本书适合作为理工科高等院校研究生、本科生教学用书，也可作为广大科研工程技术人员的自学用书。(Based on the book version of MATLAB 5.2, this book suitable as a graduate student in science and engineering colleges and universities, undergraduate teaching book, but also vast numbers of scientific research can be used as engineering and technical personnel, self-learning book.)

一个圆周卷积的代码~调用形式为y=juanji(h,x1,M) 其中，h和x1为输入，h为滤波器系数，x1为输入采样信号，输出为y,M为输入信号x1的长度。(A circular convolution of the code to call the form of y = juanji (h, x1, M) of them, h, and x1 for the input, h for the filter coefficient, x1 sampling input signals, output y, M for the input signal x1 length.)

Given 2 subscripts, j & k, KronD will return 1 if j == k and 0 if j != k. A very simple function with only a single if-else statement. Saves a bit of typing when the Kronecker Delta is needed.

舰船辐射噪声对舰船隐蔽性的重要性决定了其重要研究意义，提出了一种新的舰船辐射噪声模拟方法(The importance of the concealment of the ship radiated noise of ships determines its important research significance, this paper proposes a new method of ship radiated noise simulation)

利用基于生理的情感神经网络，包含杏仁体，丘脑，视觉神经等重要元素，可用于分类与预测，性能优越于SVM(The use of neural network based on emotional physiology, contains important elements of the amygdala, thalamus, optic nerve, etc., can be used for classification and prediction, superior performance to SVM)
