MATLAB Squeeze function __matlab

Squeeze to remove a dimension of size 1

B = Squeeze (A)

Description: B = Squeeze (a), B has the same element as a, but all but one row or column dimension (a singleton dimension) is removed. The characteristic of a singleton dimension is size (A,dim) = 1. The two-dimensional array is not affected by squeeze; If a is a row or column vector or a scalar (1-by-1) value, then B = A.

For example, Rand (4,1,3) produces an evenly distributed array, a total of 3 pages, 4 rows per page 1 columns, after squeeze, the 1-column dimension is gone, leaving only a two-dimensional array of 4 rows 3 columns. RAND (4,2,3) does not change after all squeeze because there are no 1 columns or 1 rows of dimensions.
