阵列天线的DOA估计MUSIC算法，只有几行简单的代码(DOA estimate the array antenna MUSIC algorithm, only a few lines of simple code)

This module will calculate the electrical angle between two different signals (Normally current + Voltage). once the first siganl as a reference signal and once the second signal as a reference signal.

基于matlab的迈克尔逊干涉仿真，帮助大家学习光的干涉(Based on the matlab simulation of Michelson interferometers, help you learn the interference of light )

Otsu-最大类间方差Matlab代码 最大类间方差法原理：最大类间方差法是由日本学者大津于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2 部分。背景和目标之间的类间方差 ％ 大,说明构成图像的2 部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2 部 ％ 分差别变小。(Otsu- Otsu Matlab code Otsu Principle : Otsu law by Japanese scholars in the large-1979's, is an adaptive threshold established methodology, also known as big-law, referred to Otsu. It is based on image characteristics of the gray image can be divided into the background and objectives of Part 2. Background and objectives between the between-class variance%, which meant that the two images form part of the greater difference, When some background into the wrong target or part of the background into the wrong target will lead to sub-2% difference becomes smaller.)

凸二次规划的matlab有效集算法,很有用的，值得收藏！(Convex active set quadratic programming algorithm matlab, useful, worth collecting!)

偏最小二乘法，能很好建立物质浓度和与相应的光谱矩阵的回归方程，且能对光谱阵降维和消除噪声影响。(Partial least squares, to establish material concentration and good with the regression equation of the corresponding spectral matrix array dimensionality of the spectrum and can eliminate noise effects. )
