产生m_W序列，并计算其功率谱、自相关系数和互相关系数。,M_W generated sequences, and calculate its power spectrum, since the correlation coefficient and the number of mutual relations.

Matlab源码 计算矩阵各列与其他各列的互相关系数，并按照概率分布利用直方图的形式展示出来。 该互相关系数的定义参考Michael Elad的《Sparse and Redundant Representations》p25 Definition2.3-Matlab code for mutual-coherence of a given matrix
