NoiseCancellation

说明：  对来波方向估计,并对估计误差均方差进行估计的方法(On DOA estimation, and estimation error variance estimation methods are)

改进的微分先行PID控制算法仿真源程序。 适用于输入信号跳变剧烈的场合，避免骤升或骤降时引起的系统震荡。(Improved differential forward PID control algorithm simulation source. Applied to the input signal transitions dramatic occasions, to avoid swells or sags caused when the system oscillation.)

更新一代的二型模糊降型算法-EKM算法。由KMA算法改进而成，具有更高的计算效率与优化时间(EKM algorithm (enhance Karnik-Mendel Algorithm). With higher computational sufficiency and cost less time in calculating.)

遗传算法计算最短圈MATLAB算法，矩阵C是邻接矩阵，NC是迭代次数。(Genetic algorithm for computing the shortest path)

根据潜在震源区数据，利用matlab画第五代潜在震源区图，并在鼠标点击位置编号(According to the potential source area data, using matlab draw fifth-generation potential source area map and click on the mouse position number)

说明：  马尔可夫链（Markov Chain），描述了一种状态序列，其每个状态值取决于前面有限个状态。(The Markov Chain, which describes a sequence of states in which each state value depends on a finite number of previous states)

卷积运算：取x(t)和h(t)的长度为nx,nh。平移量n=nh+nx-1，利用for和if语句实现倒序求和运算。外循环用一个for语句实现平移，通过在求和时取数组元素的顺序实现倒序求和(Convolution operation: take x (t) and h (t) of length nx, nh. Translational volume n = nh+ Nx-1, use for and if statements to achieve reverse summation operator. Outside the circle with a for statement to achieve translation, when taken in sum array elements to achieve reverse the order of summation)

四路抢答题，输入可以为四路不同信号，通过锁存抢答信号进行抢答。(Four-way scramble answer, for four different input signals, signals through the latch Answer Answer.)

说明：  matlab教程,里面有许多有用的方法.(matlab tutorial, there are many useful ways.)
