function theResult = slice(self, theSliceDim)

% ncvar/slice -- Set/get slice-dimension.
%  slice(self, theSliceDim) sets the slice information of self,
%   an ncvar object, to theSliceDim, which can be specified by
%   the dimension name, a logical-vector with the value one (1)
%   in the sequence of dimensions, or an ncdim object.  The
%   self is returned.
%  slice(self) returns a logical-vector with the value one (1)
%   in the position of the slice-dimension.  All other elements
%   are zero (0).
