Error using size and Error in cross
显示 更早的评论
if isvector(a) && isvector(b)
if (nargin == 2 && (length(a) ~= 3 || length(b) ~= 3)) || ...
(nargin == 3 && (size(a,dim)~=3 || size(b,dim)~=3))
error(message('MATLAB:cross:InvalidDimAorBForCrossProd'))
end
Error using size
Dimension argument must be a positive integer scalar within indexing range.
Error in cross (line 24)
(nargin == 3 && (size(a,dim)~=3 || size(b,dim)~=3))

Sorry Jenice , I believe you are not allowed to post the file which is copyright by Mathworks in a public forum like this.

do not pass 3 or more arguments to cross unless you are deliberately telling it which dimension to process .
you were passing 4 arguments in before and that is not defined at all.
If you need to take A cross B cross C then you will need to make multiple calls to cross.
