摘要
本文介绍线性代数中的二维代数变换与解析几何中的平面仿射变换的关系,代数变换及其变换矩阵的几何意义,各种仿射变换的矩阵表示及其矩阵性质,梳理仿射变换下的不变性质与不变量.
This paper introduces the relationship between two dimensional algebraic transformations and plane affine transformations from three aspects:the geometric meaning of the algebraic transformation and its matrix,matrices of various affine transformations and their properties,invariant properties and invariants under affine transformations.
