Outer Product是线性代数中的外积( WikiPedia: Outer Product )。也就是张量积 :

The tensor product of (finite dimensional) vector spaces has dimension equal to the product of the dimensions of the two factors:


而Exterior Product是解析几何中的外积( WikiPedia: Exterior Algebra ),又叫叉乘( WikiPedia: Cross Product )。即两个向量的法向量:

补充:
作者下面说,A与其转置矩阵相乘,相当于A的每个列向量与自身的张量积之和:
我觉得应该说A的转置乘以A方为其列向量张量积之和,有待考量。


附注:
向量点积(Dot Product),向量叉积(Cross Product)是高中数学知识
