gmres.m为迭代算法GMRES的实现-gmres.m for the implementation of the GMRES iterative algorithm

implement basic routines in Matlab and Octave (currently using Matlab R13) for simulating adaptive beamforming and filtering for antenna arrays.

这是一个Lagrange法算法-This is a Lagrange"s algorithm

应用背景公司产品需要用无源蜂鸣器产生和弦音乐，如果单纯产生不同的频率去驱动蜂鸣器，能产生不同音阶的声调，但是没有和弦音的效果，经过查找大量资料，使用电容放电实现拖音的效果，即产生了和弦音，驱动电路及源码如附件关键技术其中BP_PWR 用于控制给电容的充放电，而BUZZER则用于不同音阶的频率的产生，当BP_PWR关掉时，电容开始放电，此时BUZZER仍然有信号输出，直到电容放电完毕后，从电容的放电开始到放电结束，便产生了和弦音，效果很赞的。已经成熟应用于多个公司的产品中。

TLD is an algorithm for tracking of unknown objects in unconstrained video streams. The object of interest is defined by a bounding box in a single frame.
