%ALL    True if all elements of a vector are nonzero.
%   For vectors, ALL(V) returns logical 1 (TRUE) if none of the elements 
%   of the vector are zero.  Otherwise it returns logical 0 (FALSE).  For 
%   matrices, ALL(X) operates on the columns of X, returning a row vector
%   of logical 1's and 0's. For N-D arrays, ALL(X) operates on the first
%   non-singleton dimension.
%
%   ALL(X,'all') returns logical 1 (TRUE) if none of the elements of an 
%   array X are zero.  Otherwise, it returns logical 0 (FALSE).
%
%   ALL(X,DIM) operates down the dimension DIM of an array X.  For example, 
%   ALL(X,1) operates down the first dimension (the rows) of X.
%
%   ALL(X,VECDIM) operates on the dimensions specified in the vector 
%   VECDIM of an array X. For example, ALL(X,[1 2]) operates on the 
%   elements contained in the first and second dimensions of X.
