B = shiftdim(X,n)
[B,nshifts] = shiftdim(X)
B = shiftdim(X,n) shifts
the dimensions of
shiftdim shifts the dimensions to the
left and wraps the
n leading dimensions to the
n is negative,
the dimensions to the right and pads with singletons.
[B,nshifts] = shiftdim(X) returns
B with the same number of elements as
with any leading singleton dimensions removed. A singleton dimension
is any dimension for which
size(A,dim) = 1.
the number of dimensions that are removed.
X is a scalar,
shiftdim command is handy for creating
functions that, like
work along the first nonsingleton dimension.
a = rand(1,1,3,1,2); [b,n] = shiftdim(a); % b is 3-by-1-by-2 and n is 2. c = shiftdim(b,-n); % c == a. d = shiftdim(a,3); % d is 1-by-2-by-1-by-1-by-3.
