我有以下内容：
b = cellfun(@(x) sum(cross(u{1},x)),r,'UniformOutput',false);
我想省略总和并改为：
b = cellfun(@(x) cross(u{1},x),r,'UniformOutput',false);
然而我得到的错误是：
??? Error using ==> reshape
To RESHAPE the number of elements must not change.
Error in ==> cellcross at 4
bres = reshape(bmat,size(grid')); %reshape the get columns of bfield vectors in x y z format
原因是我不认为我在正确的地方总结。我想做总和（交叉（u {1}，r {1}））....总和（交叉（u {1}，r {n}））但结果似乎没有这样做。< / p>
