从前用matlab编的人脸识别的特征提取以及识别程序，希望有用(The previous series of face recognition using matlab feature extraction and identification procedures, seek to help)

Matlab code On Fruit quality grading

这个程序描述了MHD激波罐问题，是用python编写的，我也看得不多(Thus in the numerical approximation rounding errors and discretization errors may lead to a violation of conser- vation)

L曲线具有很多的优点，这是用MATLAB编写的病态方程的L曲线解决方法，可以通过L曲线确定所需的参数。(L curve has many advantages, it is written in MATLAB morbid equation L curve solution that will be needed through the L curve to determine the parameters.)

齐次坐标变换有很多形式，本程序证明采用不同形式时对应的转换矩阵不同(homogeneous coordinate transformation)

F16开环动力学系统模型。输入为油门及三个舵面控制，以及系统低阶、高阶选择器。输出为飞机飞行状态以及油门大小。采用Quaternion四元素法，可以有效避免俯仰角theta达到90°时数学奇异现象。(F16 open-loop dynamic system model. Throttle input and three rudder control, and system low, high selector. Output is the size of aircraft status, and throttle. Quaternion method using the four elements, can effectively avoid the pitch angle theta to 90 °, mathematics strange phenomenon.)

MATLAB7.0做得一个科学型计算器，功能齐全，欢迎大家一起下载学习。有不足的地方欢迎大家指出。(MATLAB7.0 done a scientific calculator, full-featured, with everyone welcome to download the study. There are deficiencies welcome that.)

基于小波变换的功率谱估计MATLAB仿真代码，包括小波变换的基本原理实现，mallat算法的实现，经典功率谱和现代功率谱估计的主要方法仿真比较。(Based on wavelet transform power spectrum estimation MATLAB simulation code, including the basic principles of wavelet transform to achieve, mallat Algorithm, classic and modern power spectrum power spectrum estimation of the primary means of comparison and simulation.)

说明：  基于肤色的人脸检测，肤色的提取。基于肤色的人脸检测方法，包括肤色模型建立和肤色分割过程两大部分内容。在比较了颜色空间和两种模型后，选择了在 YCbCr 空间建立高斯模型。输入图像经过相似度计算、阈值分割、最后得到人脸区域。-(matlab color detection procedure. rgb2tsl.m color model used for conversion, will be converted to RGB mode TSL model. realize skin.m color detection, color region is white, non-color region is black.)

最小二乘算法来实现esprit算法，该代码已经在matlab中运行过绝对可以放心使用(Least squares algorithm to achieve esprit algorithm, the code has been run in matlab absolutely safe to use)
