Shift right and left with 3D data by matlab

I have one code to shift left and shift right with 2D data in Matlab. There are codes

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) ];

I want to apply above codes to 3D data input. How to modify above codes for 3D data? Thank you

function shift = shiftL3D(M)


function shift = shiftR3D(M)

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) )
