奇异值分解的方法求解方程,奇异值分解(SVD)是计算机视觉领域中一种使用最为广泛的矩阵分解技术。我们已经知道...关于使用SVD分解方法求解AX=0方程的一点说明(Singular value decomposition (SVD) is one of the most widely used matrix decomposition techniques in computer vision. We already know... A note on the use of the SVD decomposition method to solve the AX=0 equation.)

说明：  通过四元素解算姿态，对四元数进行解算，处理相应的四元数(Solve the attitude through four elements, solve the quaternion, and process the corresponding quaternion)

ucOS+ucGUI人机界面实验源码 加入触摸屏校准功能。 >> 校准后触摸屏参数保存在STM32芯片自身的Flash中。 >> 当第一次启动程序或者全部擦除芯片后第一次启动将会执行校准。 >> 也可以在设置功能中选择“触摸屏校准”手动执行校准，前提是当前触屏参数和真实值相差不大，可以进入到触摸屏校准选项。(UcOS+ucGUI human interface experimental source)

说明：  分子动力学软件运行后的应力提取，借此可以得出应力应变曲线(After the molecular dynamics software runs, the stress-strain curve can be obtained)

恒流驱动和提 高LED的光学效率是LED 应用设计的两个关键问题，本文首先介绍大功率LED的应用及其恒流驱动方案的选择指南，然后以美国国家半导体(NS)的产品为例，重点讨论如何巧妙应用 LED恒流驱动电路的采样电阻提高大功率LED的效率，并给出大功率LED驱动器设计与散热设计的注意事项。-LED constant current drive and to improve the optical efficiency of LED application design of two key issues, this paper describes the application of high-power LED constant current driver and the choice of the program guide, and then the United States National Semiconductor (NS) products, for example, focus on how skillful application of LED constant current driver circuit of the sampling resistor to improve the efficiency of high-power LED, and gives high-power LED driver design and thermal design considerations.
