spectrum of signal comminucation field

用matlab基本算法之一，MUSIC方法估计波达方向(One of the basic algorithm with matlab, MUSIC DOA estimation methods)

说明：  区域生长 区域生长的一个关键是选择合适的生长或相似准则， 大部分区域生长准则使用图像的局部性质。(A key growth region growing area is to select the appropriate growth or similar criteria, the local nature of most of the regional growth guidelines for using the image.)

说明：  激光变换中的GS算法,ORA算法，用matlab编程的。(Laser transformation in the GS algorithm, ORA algorithm, using MATLAB programming.)

SONAR_ANAL is a callback for the sonar demo

最小二乘拟合，包括3次，9次，15次曲线拟合(Least-squares fit, including three times, nine times, 15 times Curve Fitting)

说明：  基于matlab的衍射模拟，在毕业设计的时候顺便参考做的，有问题的话欢迎指出(Matlab simulation based on the diffraction, when the way in the graduate design reference do have problems, then welcome to point out)

说明：  根据脉冲序列，使用s域z域之间的转换，求系统的脉冲响应传递函数(According to pulse sequence, the use of s-domain conversion between z-domain, and the system impulse response transfer function)

最小二乘窄带干扰消除，使用单步线性预测器（D=1）(NBI, when D=1)

压缩感知：2维图像的压缩感知SL0重构算法，是本人精心编写调试好的，请放心使用。(cs:2 dimensional image compressive Sengsing uingsing SL0 reconstruction algorithm )
