You can use it to make the singularity spectrum of the cantor set .The syms is 0.4P2.

说明：  实现KALMAN滤波算法，通过跟踪，估计物体运动轨迹。(achieve Kalman filtering algorithm, by tracking estimated object trajectories.)

LTE 中文协议，很经典全面的讲LTE的资料，做好笔记看一段时间很有用的。(LTE protocol LTE physical layer General description Multiplexing and channel coding)

提供了四种不同的采集数据，001和002是FSK2信号，003和004文件是FSK4信号，两个mat文件是广播接收FM信号和对讲机接收的FM信号，这两个文件都是基带信号，其他六个都是中频信号，载波分别是250KHz（001-004文件）和21.6MHz（AM信号abc0和abc1文件），提供这几个采集到的数据文件供大家进行程序的测试和修正(Provides four different data acquisition, 001. 002 is a the FSK2 signal, 003 and 004 file is FSK4 signal, two mat file is the FM signal received by the broadcast receiving FM signals and intercom, these two files are a baseband signal, the other six are intermediate frequency signals, the carrier is 250KHz (001-004 files) and 21.6MHz (AM signal abc0 and the abc1 files), the provision of several data files collected for program testing and remediation)

Jacobi矩阵一般是坐标变换时用的——这个坐标系的坐标依次对那个坐标系的坐标求偏导数即得Jacobi矩阵。积分时从直角坐标变到球坐标、极坐标肯定要在积分号里乘上Jacobi矩阵的行列式。 若其特征值全为正，则此Jacobi矩阵正定，即它的任何二次型都大于零。并且如果是对称Jacobi矩阵，还可以实相合于一个单位阵。是比较强的条件。矩阵A的特征值是这个关于x的方程的所有根 det(A-xI)=0(Jacobi)
