基于小波变换中SVD变换的心电信号处理实现，有心电信号原始数据(ECG signal processing based the SVD transform the wavelet transform achieve, determined to electrical signals raw data)

fcm的过程，有图像界面不知道咋传，可以根据代码自己加按钮(fcm the process, there do not know ye pass graphical interface, you can add the button under the code itself)

A Costas loop is a phase-locked loop used for carrier phase recovery from suppressed-carrier modulation signals, such as from double-sideband suppressed carrier signals. It was invented by John P. Costas at General Electric in the 1950s. Its invention was described as having had "a profound effect on modern digital communications".

改进的分段线性表示方法，含有四种基本算法，自顶向下，自底向上，滑窗，以及滑窗式自底向上算法。是流行的降维、分类算法。改进之后，所得出的线段是连续的，解决了离散线段带来的不便。(Rewised PLR algorithms inclusing four basic methods: top down, bottom up, sliding window and sliding window bottom up. PLR is a popular algorithm for classification and demension reduction. )

说明：  MDF多变量频域设计工具箱，可方便的绘制格西高林圆及Nyquist曲线(MDF multivariable frequency domain design tool, can easily draw the circle and Geshe Nyquist curve of the high forest)

地理坐标系转地磁坐标系，输出磁地方时等参量(Geographic coordinates turn geomagnetic coordinate system, the output magnetic local time and other parameters)
