判断矩阵的加权对数最小二乘排序法

The weighted logarithmic least square method of the judgement matrix

该迭代方法与基于Wishart距离的迭代分类方法相比，不需要矩阵的求逆运算和矩阵的对数运算，降低了迭代过程的计算量，也不再需要目标的先验信息，扩展了其适用范围。

This new method not only reduces the compute , but also needs not apriority information of the targets compared with Wishart classifier .
