在电话拨号时 ，每个按键都使用双频信号进行区分的，本MATLAB程序就是用来模拟发送号码的发送和接受过程，并发出按键音。(In a telephone dial-up, each button using the dual-band signal distinction, the MATLAB program is used to simulate the sending number to send and accept the process and issue the key tone.)

基于matlab的粒子滤波目标跟踪算法，初学者很有用(Matlab-based particle filter target tracking algorithms , very useful for beginners)

分析了电压型控制模式下的逆变器并网的电路结构和数学模型，提出了基于重复控制技术的光伏逆变器并网控制策略，仿真和实验结果表明方案满足逆变器并网要求。(Voltage control mode inverter grid circuit structure and mathematical model is proposed based on repetitive control technology photovoltaic inverter grid control strategy, simulation and experimental results show that the program inverter to meet and network requirements.)

适合使用NUVOTON nuc501 做开发的参考。(The NUC501 is an ARM7TDMI-based MCU, specifically designed to offer low-cost and high-performance for various applications, like interactive toys, edutainment robots, and home appliances. It integrates the 32-bit RISC CPU with 32KB high-speed SRAM, crypo engine with OTP key, boot ROM, LDO regulator, ADC, DAC, I2C, SPI, USB2.0 FS Device, & GPIO into a cost-affordable whil feature-rich micro-controller.)

SPWM控制的逆变器simulink范例。通过更改开关的占空比来调节输出电压(Simulink example SPWM inverter control. By changing the switch duty cycle to regulate the output voltage)

INTRODUCTION FOR MODEL PREDECTIVE

在人脸局部图像中定位嘴的中心。MATLAB环境代码，配有实验用图。具体步骤：对输入图像进行二值化处理-标注二值图像中的连通分量-找出最大的连通分量-计算最大联通分量中心。《精通Matlab数字图像处理与识别》(The face part image is positioned in the center of the mouth. MATLAB environment code, with experimental Fig. Specific steps: input image binarization processing- marked binary images connected components- find the largest connected component- component to calculate the maximum Unicom center.
