Finally, in order to fix on the position of nonzero lattice vector effectively, that is, to deal with zero lattice vectors effectively, the concept of significant map is introduced into.

最后为了有效确定非零格点的位置，也就是为了有效地处理零格点，又引进了重要图的概念。

Any TRUE if any element of a vector is a nonzero number or is logical 1 (TRUE).

判断向量中是否存在非零元素，若存在返回1，否则返回0(忽略nan元素)。
