有限维线性空间上的投影与幂等矩阵

Idempotent Matrix and Projection in Infinite Dimentional Linear Space

利用线性变换与矩阵的对应关系,讨论了复数域C上的n维线性空间V上的投影变换与幂等矩阵之间的关系。

Making use of the corresponding relation between linear transformation and matrix,We discuss the corresponding relation between idempotent maxtrix and projection in the n dimentional linear space V on complex field.
