Create a 4-by-2-by-3-by-5 array. Shift the dimensions 2 positions to the left, wrapping the first 2 lengths to the last 2 dimensions.

A = rand(4,2,3,5); B = shiftdim(A,2); size(B)

ans =1×43 5 4 2

Shift the dimensions 2 positions to the right, resulting in 2 leading dimensions of length 1. Shifting to the right does not wrap the dimension lengths.

C = shiftdim(A,-2); size(C)

ans =1×61 1 4 2 3 5

Shift the dimensions of an array.

Compute a 5-D arrayA, and remove the leading dimensions of length 1. Theshiftdimfunction shifts 2 dimensions and returns the 3-D arrayB.

A = rand(1,1,3,2,4); [B,nshifts] = shiftdim(A); nshifts

nshifts = 2

size(B)

ans =1×33 2 4

Shift the dimensions ofBtwice to the left.

C = shiftdim(B,2); size(C)

ans =1×34 3 2

Shift the dimensions ofConce to the right.

D = shiftdim(C,-1); size(D)

ans =1×41 4 3 2
