我有两个9x9个矩阵,A和B。
我想建立一个大的矩阵C,其模式如下:
A B B B B B
B A B B B B
B B A B B B
B B B A B B
B B B B A B
B B B B B A
As you can see, the A matrices are on the diagonal, the B are everywhere else. I m trying to create a code so that this pattern continues no matter how great the dimensions are.
E.g. 10 matrices x 10 matrices still has matrix A along the diagonal and B s everywhere else.
最好使用马hor和散射或像混血这样的东西? 我不将这些矩阵表A和B已经包含信息。
感谢大家花时间阅读。
如何(定义)
maskcell = repmat( {ones(size(A))}, 1, 10 );
maskdiag = blkdiag( maskcell{:} );
AA = repmat( {A}, 1, 10 );
AD = blkdiag( AA{:} );
BB = repmat( B, 10, 10 );
C = BB .* (maskdiag == 0) + AD
在下文完全有效的评论之后,我添加了面罩,以确保正确的东西从C中挑选。
C=B(~eye(size(B))+A(eye(size(A)))应当获得你想要的东西。 或许可以更快地将眼睛的使用结合起来......
kron(eye(10), A) + kron(~eye(10), B)
So i have a set of four points in 3D Space. P1 [0, 0, 0] P2 [128, 0, 0] P3 [0, 128, 0] P4 [128, 128, 0] Which I m then projecting orthographically to the screen effectively giving me two ...
Suppose I have an AxBxC matrix X and a BxD matrix Y. Is there a non-loop method by which I can multiply each of the C AxB matrices with Y?

I m getting a weird error when training a glmnet regression. invalid class "dgCMatrix" object: length(Dimnames[[2]]) must match Dim[2] It only happens occasionally, and perhaps only under larger ...
I need to store a 2d matrix containing zip codes and the distance in km between each one of them. My client has an application that calculates the distances which are then stored in an Excel file. ...
