squeeze (MATLAB Function Reference)

Remove singleton dimensions

B = squeeze(A)

Description

B = squeeze(A)

returns an array B with the same elements as A, but with all singleton dimensions removed. A singleton dimension is any dimension for which
size(A,dim) = 1.

Examples

Consider the 2-by-1-by-3 array Y = rand(2,1,3). This array has a singleton column dimension -- that is, there's only one column per page.

Y =

Y(:,:,1) =       Y(:,:,2) =
    0.5194           0.0346
    0.8310           0.0535

Y(:,:,3) =
    0.5297
    0.6711

The command Z = squeeze(Y) yields a 2-by-3 matrix:

Z =
    0.5194    0.0346    0.5297
    0.8310    0.0535    0.6711
