sign pattern

When there's no explicit negative pattern, a leading minus sign is assumed in combination with the positive pattern.

没有显式的负数模式时，假设正数模式中包含前置的负号。

The potential idempotence of nonnegative sign pattern matrix is described.

刻划了非负符号模式矩阵的强迫(蕴含)幂等性.

A square sign pattern matrix that does not have a zero row or zero column is sign potentially orthogonal ( SPO) if every pair of rows and every pair of columns allow orthogonality.

一个没有零行或零列的n阶符号模式矩阵是符号蕴含正交的，若每一对行和列向量都是蕴含正交的。

If the pattern specifies a leading minus sign for negative input, a trailing minus sign is ignored.

如果该模式指定前置负号为负输入，后置负号将被忽略。
