Matlab code for PIT techniquw

N-Point FFT using fixed-point toolbox of MATLAB

说明：  利用Grubbs法的思想剔除数据集中的异常值;用Lagrange插值法对缺失数据补充(Delete outliers in a set by the Grubbs rule.)

说明：  偏最小二乘工具箱，解压后可直接在matlab中调用m文件(Partial least squares toolbox, after decompression can be directly invoked m file in MATLAB.)

回波抵消器中常用的几种自适应滤波算法有LMS, NLMS, RLS等算法。对现有主要算法的性能进行了分析，并对优缺点进行评价和比较。为了在收敛速度和运算量之间得到很好的折衷，对NLMS算法改进，得到了 PNLMS(Echo cancellation devices commonly used in adaptive filtering algorithm has several LMS, NLMS, RLS, such as algorithms. The main algorithm of the existing performance analysis, and evaluation and comparison of the advantages and disadvantages. For the convergence between computing speed and a good compromise on the NLMS algorithm improvements have been PNLMS)

linear discriminant analysis

在制定的位置显示图像，还可以改变位置来显示位置，可以自定义横坐标和纵坐标的值。(Position in the development of display images, but also can change the location to display the location, can customize the abscissa and ordinate values.)

说明：  求模极大值的程序MATLIB源码,可以用此方法来判断时间序列的奇异点,并根据它来恢复信号.(modulus maxima for the procedure MATLIB source, you can use this method to determine the time sequence of singular point, and according to restore its signal.)
