说明：  利用mean shift实现图像分割和平滑(utilize the mean shift method to achieve image segementation and flatness.)

波束域降阶Root-MUSIC算法,在子阵分解降阶的基础上,进一步将多项式的求根阶次降到与源数目相同,提出了求解降阶多项式的方法。该方法最大程度地减少了求根多项式的阶次和求解多项式的次数,并保持了Root-MUSIC算法的优良性能。显著降低运算量是其最大优点,仿真结果验证了降阶算法的有效性,并比较了不同阶次波束域Root-MUSIC算法的估计性能。 (Beamspace Reduced Order Root-MUSIC algorithm, based on the reduced-order sub-array decomposition further order of the polynomial rooting down with the same number of sources, proposed to solve the reduced-order polynomial method. This method minimizes the number of polynomial order and solving polynomial rooting and maintain the excellent performance of Root-MUSIC algorithm. Significantly reduce the amount of computation is its biggest advantage, simulation results show the effectiveness of the reduced-order algorithm, and compare the performance of different estimates of the order beamspace Root-MUSIC algorithm.)

解凸优化的工具包,使用简单，有使用指南。适用于最新版的matlab(the tool for convex optimization, used easily . the userguide is attached)

说明：  matlab 程序，可用于地震正演模拟中的震源，数据处理等(Ricker wavelet,seismic modeling)

在这个例子中，我们对有三条固定路径的AWGN多径信道中的QPSK系统进行BER性能仿真，并与在理想的AWGN信道（没有多径）中同样系统的BER性能进行比较。(In this example, we have three fixed-path multipath AWGN channel QPSK system BER performance simulation, and in an ideal AWGN channel (no multipath) in the same system BER performance comparison Progressive line.)

汽车ABS仿真abs又叫做防止刹车抱死系统。以往的刹车，通常是四轮同时有闸将轮胎抱死。达到减速停车效果。(Simulation of automotive ABS)
