采用KSVD算法通过训练的方法来构造稀疏过完备字典，在使用时一定要确保已装有ompbox9。可用于语音，图像信号处理等的稀疏字典构造(KSVD algorithm using the method of training to construct the sparse over-complete dictionary, in use, make sure have been installed ompbox9. Can be used for the sparse dictionary construction in voice, image signal processing )

插值算法是一类重要的线性搜索方法，其基本思想是在搜索区间中不断用低次插值多项式来近似目标函数。该程序是用二次插值算法求区间上的无约束最优化解。(Interpolation algorithm is one important class of linear search method, its basic idea is constantly in the search interval with a low polynomial interpolation to approximate the objective function. The program is used quadratic interpolation algorithm for unconstrained interval on optimal to resolve.)

matlab环境下PLL经典例程，包含一阶和二阶锁相环。(matlab environment PLL classic routines, including a first-order and second-order phase-locked loop.)

说明：  在阵列信号处理中,可以对信号的来波方向进行估计,并计算其估计误差!(In array signal processing, the signal can be estimated to wave direction, and calculate the estimation error!)
