关于幂等变换性质的讨论

The Discussion on the Nature of Idempotent Transformation

线性变换是最基本的一种变换,是线性代数研究的一个主要对象,而幂等变换是一类特殊的线性变换,它不仅具备线性变换的一般性质,更由于它的特殊性,还具备了不同于一般线性变换的特殊性质.

Linear transformation is the most fundamental change, and it is the major object that linear algebra is researching on, but the idempotent transformation is a special linear transformation, which not only has the general properties of linear transformation, but has the special nature different from the general linear transformation.
