严格按书上传统原子库的MP稀疏分解~~~~~~~~~~~~(In strict accordance with the traditional book MP sparse decomposition atomic library)

calculating partial differentiation of the iris contours.

基于MVDR算法，计算两个信号的相关性的函数。(This program computes the coherence function between 2 signals x1 and x2 with the MVDR method. This algorithm is based on the paper by the same authors: J. Benesty, J. Chen, and Y. Huang, "A generalized MVDR spectrum," IEEE Signal Processing letters, vol. 12, pp. 827-830, Dec. 2005. x1, first signal vector of length n x2, second signal vector of length n L is the length of MVDR filter or window length K is the resolution (the higher K, the better the resolution))

改程序用于在一组信号中检测出最大值，即峰值检测(maxima detection， /peak detection)

通过强大和安全的形象散列 非负矩阵因式分解，在信息取证与安全，376-390，2007年IEEE交易。NMF-NMF-SQ哈希( V. Monga, and M. K. Mihcak, Robust and secure image hashing via non-negative matrix factorizations, IEEE Transactions on Information Forensics and Security, 2(3), 376-390, 2007. NMF-NMF-SQ Hashing)

用matlab实现的Hilbert-huang变换算法。(Implemented with the matlab Hilbert-huang transform algorithm.)
