Image_Spatial_Filtering

给出两个chirp信号相加后，由瞬时频率定义求出的瞬时频率曲线，说明瞬时频率的不确切性；(The sum of two chirp signals are given, after the definition of instantaneous frequency derived from the instantaneous frequency curve, indicating lack of precision in the instantaneous frequency )

本程序主要用来在设计广义切比雪夫滤波器时，根据给定的指标要求能综合处其所需要的耦合矩阵的耦合系数，从而方便进行下一步的设计(This procedure is mainly used in the design of generalized Chebyshev filter can be integrated Department, they need the coupling matrix of the coupling coefficient, according to the target set by the requirements, in order to facilitate the design of the next)

这是MATLAB7.0编程基础的源程序，全部的源程序，自己使用后感觉不错的 大家可以分享一下(MATLAB7.0编程基础-源程序)

说明：  会跳动的红心，比较可爱版，可以编译上自己的名字(Beating hearts, lovely versions, can compile their own names)

说明：  一篇很好的matlab的PDEtool工具箱使用文献.感兴趣的可以看看.(A good use of matlab toolbox of PDEtool literature. Interested can look at.)

说明：  利用潮位数据计算理论深度基准面，其中各分潮系数需修改(Calculating theoretical depth datum using tidal data)
