差分方程求解公积金问题-Matlab实验课程学习资料，附源码(Differential equations for solving provident fund-Matlab experimental course learning materials)

TargetLink Features and Migration Version 2.0

电力电子基本模块的simulink仿真，包括有buck、buck-boost、双极性spwm、单极性spwm仿真实现，已通过测试！(Power electronics simulink simulation of basic modules, including buck, buck-boost, bipolar spwm, unipolar spwm Simulation, has been tested!)

说明：  核极限学习机，引入核函数解决ELM求解问题，一旦参数选定，结果就稳定下来，不再混入随机。在原来版本上加入自己理解改写，使得代码更容易理解。((Kernel extreme learning machine, kernel function is applied to deal with ELM to solve the problem, once the parameters selected, the result is stabilized, not randomly in the original version on becoming a member of their understanding, makes the code easier to understand))

常用的DIP28封装库，适用于Autium Designer 的元件常用PCB封装(Common dip28 package library, common PCB packaging for autiumdesigner components)

基于STM32F407实现人脸识别和指纹识别的考勤系统硬件设计。(Hardware Design of Time and Attendance System Based on STM32F407 for Face Recognition and Fingerprint Identification.)

说明：  包含主板，驱动板，运放等所需全部板工程文件(Contains all board engineering files required for motherboard, driver board, op amp, etc.)

借鉴了主成分分析算法（PCA），实现了图像的加水印，去噪，加噪声等功能，具有丰富的参数选项。( It draws on principal component analysis algorithm (PCA), Realize image watermarking, de-noising, plus noise and other functions, It has a wealth of parameter options.)
