Kalman-filtering

非常简单的在matlab下生成M序列的程序(A very simple M sequences generated in the matlab program)

In this letter, we propose anovel family of windowing technique to compute mel frequency cepstral coefficient (MFCC) for automatic speaker recognition from speech. The proposed method is based on fundamental property of discrete time Fourier transform (DTFT) related to differentiation in frequency domain. Classical windowing scheme such as Hamming window

计算矩阵各点之间的距离，并选取合适的点，适用于大型矩阵的计算(Calculate the distance between the points of the matrix)

说明：  拉东变换和反变换，去除多次波，压制多次波(radon and iradon multiple wave remove)

说明：  改过的ISOMAP算法，较之前的算法速度更快，可视化效果更好(Turn over the ISOMAP algorithm, faster than the previous algorithm, visualization better)
