在Matlab中如何做(m，n，k)*(n，k)=(m，k)? [英] How to do (m,n,k) * (n,k) = (m,k) in matlab?

问题描述

我发现了以下相关问题: 乘法列MatLab中具有3d矩阵的2d矩阵切片的矩阵的计算

I have found this relevant question: Multiply columns of a matrix with 2d matrix slices of a 3d matrix in MatLab

我有同样的问题，但在我的情况下，每个切片的m可能有所不同.有没有一种方法可以使用

I have the same problem but in my case m can vary for each slice. Is there a way to do that with mtimesx ? Because m varies, my 3d tensor is stored as a list of cells, each containing a matrix. Also my 2d matrix is rather a list of cells each containing a vector.

有没有一种方法可以在没有for循环的情况下进行乘法运算?

Is there a way I can do this multiplication without a for loop?

推荐答案

由于您的数据已经存储在单元阵列中，因此您可以使用

Since your data is already stored in cellarrays, you can use cellfun

res = cellfun( @(x,y) x*y, mnkCell, nkCell, 'UniformOutput', false );
