用matlab语言实现图像的主色调提取，算法简单，适合初学者。(Matlab language used to achieve the main colors extracted image, the algorithm is simple, suitable for beginners.)

某国外知名大学的数字信号处理算法教材，使用m语言进行编程。(AlgorithmCollectionsforDigitalSignalProcessing，E.S. Gopi National Institute of Technology, Tiruchi, India)

说明：  由于matlab提供了一些很有用的计算方法 但是大部分用户只用到其中一部分的功能 所以写了一个包括解方程，矩阵计算，排序功能的代码(As matlab provides some very useful method but most users only use part of the function it was a including solving equations, matrices, and sorting code)

matlab编程：主要是对gngauss函数定义介绍(matlab Program：Mainly for gngauss function definitions introduced)

Using high-order cumulants of MPSK signal modulation recognition, Calculated transmission characteristics and reflection characteristics of the one-dimensional photonic crystals, Principal component analysis of multivariate data analysis projection.

说明：  捷联惯导系统导航解算. 根据600秒的指北方位捷联系统的数据进行导航解算，飞行高度不变，采样周期0.01s.(Strapdown inertial navigation system navigation solution. Based on the 600 seconds that the north-bit data SINS navigation solution, the same altitude, sampling period 0.01s.)
