通过matlab使用3D数据左右移动

Question

我有一个代码向左移动并在Matlab中使用2D数据向右移动。有代码

function shift = shiftL(M)
  shift = [ M(:,2:size(M,2)) M(:,size(M,2)) ];

function shift = shiftR(M)
  shift = [ M(:,1) M(:,1:size(M,2)-1) ];

我想将以上代码应用于3D数据输入。如何修改上述3D数据代码？谢谢

function shift = shiftL3D(M)


function shift = shiftR3D(M)

Answer 1

function shift = shiftL3D(M)
    shift = cat (3, M(:,:,2:size(M,3)) , M(:,:,1) );
function shift = shiftR3D(M)
    shift = cat (3,M(:,:,end), M(:,:,1:size(M,3)-1) )

Answer 2

function shift = shiftL3D(M)
  shift = cat(size(M,3),M(:,:,2:size(M,3)), M(:,:,1));

function shift = shiftR3D(M)
  shift = cat(size(M,3),M(:,:,end),M(:,:1:size(M,3)-1));
