常用跳频，扩频信号的调制与解调，主要用于通信及数字信号处理领域(Commonly used frequency hopping, spread spectrum modulation and demodulation of the signal, mainly used in the field of communications and digital signal processing)

说明：  平方根升余弦脉冲实例。两个SQRC滤波器的级联组合就成为一个零ISI的滤波器。此程序用于获得平方根升余弦脉冲。(Square root raised cosine pulse instance. Cascade combination of the two SQRC filters to filter a zero ISI. This procedure used to obtain the square root raised cosine pulse.)

DNMF在matlab中的实现，基于R语言的示例改写(Discriminant Non-Negative Matrix Factorization aims to extend the Non-negative Matrix Factorization algorithm in order to extract features that enforce not only the spatial locality, but also the separability between classes in a discriminant manner.)

说明：  坐标转换，从地固坐标系的笛卡尔直角坐标到大地坐标，考虑到不同的椭球参数。(function to calculate the geodetic Earth-fixed coordinates from Cartesian coordinates )

说明：  这是matlab编写的一组神经网络的程序,非常好用,只需要改动一些参数即可(It is written in a matlab neural network program, very easy to use, you can only change some parameters)
