这个也是关于空间谱的matlab 挺好的 可以(This is on the spatial spectrum of matlab can be quite good)

this is a database for jus withe 218 samples and 700 features

一段关于POV技术的取模功能代码,在matlab中需要先导入图片，二维码另存为img(a set of code about POV technology )

分前后两级，前级boost升压电路，后级三相全桥逆变(Points before and after the two pre-boost boost circuit, after three-phase full-bridge inverter)

用于三维重建的反投影滤波,X-ray，CT，SPECT等图像重建(3D reconstruction)

粒子群优化算法，粒子群优化算法基本流程，稍加修改即可应用(Particle Swarm Optimization)

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.)

M/M/1 模型,主要用来求解单对单服务台的模型，过程比较简介，适合任何分布(M/M/1 model, mainly used to solve the one-on-one help desk model, the process is relatively brief, suitable for any distribution)

用BP网络完成函数的逼近 P网络通常有一个或多个隐层，隐层中的神经元均采用sigmoid型变换函数，输出层的神经元采用纯线性变换函数。本例应用一个两层BP网络来完成函数逼近的任务，其中隐层的神经元个数是5。(network to be completed by BP function approximation P networks usually have one or more hidden layer, a hidden layer neurons are used sigmoid-type transformation function, the output layer neurons using pure linear transformation function. The application of a two-tier cases BP network function approximation to complete the task, hidden layer neuron number is 5.)
