我可以在 nD 矩阵上使用 mldivide“\”而不在 MATLAB 中使用 for 循环吗？

Question

Could I use mldivide ( \ ) on an n-dimensional matrix in MATLAB without using for loops? For example, if I have X=rand (5,5,2,3,6) and Y=[0;0;0;0;1]; , can I slice every 5*5 array along the other dimensions to solve it against Y ?

Answer 1

I solved it with the help of Bruno Luong and his multisolver found here . The code below can solve any number of dimensions, considering the first two dimensions are of the same size.

M=rand(5,5,2,3,6);
RHS=[0;0;0;0;1];
sx = size(M);
sy = size(RHS);
dx = ndims(M);
MSOL=MultiSolver(reshape(M,sx(1),sx(2),[]),RHS);
MSOL = reshape(MSOL, [sx(2) sy(2) sx(3:dx)]);
