矩阵的外积以前没注意到! 在matlab上为对应行的外积, 见其help说明
C = cross(A,B) returns the cross product of the vectors A and B. That is, C = A x B. A and B must be 3-element vectors. If A and B are multidimensional arrays, cross returns the cross product of A and B along the first dimension of length 3.

楼上说的是向量的点积dot和叉积cross运算,这个我了解!
根据我的推断,矩阵的外积中两个矩阵的维数是任意的,并不限定于叉积运算的3个元素。请专家指导一下到底矩阵的外积是怎么定义的,我算东西急用!
