%ALL   True if all pixels in an image are non-zero.
%   VALUE = ALL(B) gets true if all pixels in B are non-zero. It works
%   independently on each tensor element.
%
%   VALUE = ALL(B,M) only tests the pixels within the mask specified by
%   the binary image M, and is equivalent to ALL(B(M)).
%
%   VALUE = ALL(B,M,DIM) tests over the dimensions specified in DIM.
%   For example, if B is a 3D image, ALL(B,[],3) returns an image
%   with 2 dimensions, containing the 'all' projection over the third
%   dimension (z). DIM can be an array with any number of dimensions.
%   M can be [].
%
%   VALUE = ALL(B,'tensor') works over the tensor elements, returning
%   a scalar image of the same size as B.
%
%   COMPATIBILITY NOTE:
%   The behavior of ALL(B), with B a tensor image, has changed since
%   DIPimage 2. Previously, it operated on the tensor elements, which
%   is currently accomplished with ALL(B,'tensor').
