说明：  用MATLAB实现非线性规划中的最速梯度法，并有GUI图形(MATLAB realization of non-linear programming used in the steepest gradient method, and graphical GUI)

用平面波展开法计算二维声子晶体带隙，里面附有注释，可以学习(With two-dimensional plane wave expansion method to calculate the phononic band gap, which is annotated, you can learn)

此程序主要是基于希尔伯特-黄变换编写的MATLAB程序，用于搞科研的工作者们。(This program is mainly based on Hilbert- Huang Transform written MATLAB program for workers who engage in scientific research.)

基于matlab环境，利用谱减法实现语音信号增强(Matlab-based environment, using spectral subtraction to enhance voice signal)

假定半波长间隔均匀分布线列布阵的阵元数N=16，若入射平面波为f=62.5Hz的正弦信号，信号持续时间为0.4s， 系统采样频率 =1 KHz,阵列加权为均匀加权，分别给出 a)当平面波信号分别从 0,10,20,30,40,50,60,70,80,90,100度方向入射时，指向90度的波束形成器的输出序列； b)当平面波信号分别从0:1:180度方向入射时，指向90度的波束形成器的输出序列经过平方求和后的分贝数输出（把所有181个输出绘制在同一幅图中)(Assuming N=16, f=62.5, fs=1KHz, uniform weight, and the code gives: a) 90 degree response when incidence angles are: 0: 10: 100 degrees b) 90 degree spectral response when incidence angles are: 0:1:180 degrees )

程序是模糊MPPT控制，包括三个模块，光伏电池模块 模拟boost电路模块 (mppt MPPT control program is vague. Consists of three modules, photovoltaic module analog boost circuit module)

三相逆变桥PWM电流滞环控制Simulink仿真，另加一滤波器观看PWM经过低通滤波后的波形，适合电力电子初学者(Three-phase PWM inverter current hysteresis control Simulink simulation, plus a watch PWM filter through after the low-pass wave filter for power electronics for beginners)

压缩包内是一个word文档，文档里边包含了许多各种各样的matlab对图像的处理子程序(Compression package is a word document, the document inside contains a variety matlab image processing subroutine)
