CvEM::COV_MAT_DIAGONAL - a covariation matrix of each mixture may be arbitrary diagonal matrix with positive diagonal elements, that is, non-diagonal elements are forced to be 0's, so the number of free parameters is d for each matrix.

According to this characteristic, the search matching method of this diagonal line in this calculation is to regard the main diagonal lines as the superior searched route, discard the elements far from the main diagonal lines and it won't generate matching matrix when actually realized. Just regard the present search point as the start point, search matching elements at the small rectangle from the bottom right, regard the element when found as the new start point, so this can happen repeatedly until the ends of the two strings.

根据这个特点，本算法中的对角线搜索匹配算法以主对角线为优先搜索路径，抛弃了离主搜索路径太远的元素，实际实现时，并不需生成匹配矩阵，只以当前搜索点为起点，向右下方向一个小矩形区域上搜索匹配的元素，找到匹配的元素后即以该元素为新的起点，这样无回溯地重复进行直到两个串的未尾为止。

A determinant in which all elements are zero except the elements of the principal diagonal and the elements immediately above and below this diagonal is called a continuant.

一个行列式除了主对角元素以及紧靠对角线的上面和下面的元素外，所有的元素均为零者叫做连行列式。

Some necesarry and sufficient coditions for generalized diagonal dominance for matrices are discussed by using the determinant and the closed convex cone generated by matrices column vectors. This paper, thus provides some new methoods for determining the generalized diagonal dominance in matrices.
