模式识别作业，用近邻函数法分类的matlab程序，classification using matlab(Pattern recognition operations, with neighbors matlab function method classification procedure, classification using matlab)

一阶导数的常用差分逼近 求解df的差分逼近 flag标记使用的差分算法 算法来自周超红的《一阶导数的差分逼近汇总》 可按照里边的算法构造更高阶的差分逼近(First derivative of the common difference approximation approach for solving differential df flag tag algorithm using the difference method from the week of super-red " first derivative of the difference approximation of summary" can be constructed in accordance with the algorithms inside the differential approximation of higher order)

对偶单纯型 最优化的一个作业 需要的可以参考下~(Dual simplex)

信息隐写 构造完美矩阵编码嵌入 SPIE2011_stego_design_v0.9(Information steganography construct the perfect matrix coding embedded)

说明：  三相电压源型PWM整流器，采用了电压电流双闭环的控制策略(The three-phase voltage source PWM rectifier )

MATLAB的命令和函数有很多，在实际工作中我们往往不能将所有函数和命令全记住，将MATLAB的命令和函数罗列出来，有助于大家在平时的查询。(MATLAB commands and functions have a lot of that in practice we often do not work all the functions and commands to remember the whole, the MATLAB command and function set out to help everyone in the usual inquiries.)

When the P89LPC90x is in programming mode all pins that are not used for programming are tri-stated. During programming mode the reset pin has a weak pull-up resistor.(When the programming is in a mode 'll pins that are not used for programming are tri- stated. During programming mode the reset pin has a weak pull-up resistor.)
