Arrays 在Matlab中，将存储在两个多维数组中的向量相乘，而不使用for循环？

我尝试了bsxfun，但找不到任何合适的操作。

您可以将数组乘法与

bsxfun一起使用。

%In MATLAB: I have stored vectors A and B in two multidim. arrays:
A = rand(4,1,4); B= rand(1,3,4);

%Now I want to create multidim array C(3,3,4) 
%by multiply A and B in each dim i (:,:,i) without a for-loop.

%So instead of these four operations below, just perform one operation e.g. C=A*B.

C(:,:,1)=A(:,:,1)*B(:,:,1);
C(:,:,2)=A(:,:,2)*B(:,:,2);
C(:,:,3)=A(:,:,3)*B(:,:,3);
C(:,:,4)=A(:,:,4)*B(:,:,4);

这对我来说是新的。我看了两遍才知道发生了什么。很好，我穿新的。我看了两遍才知道发生了什么。很不错的。
