% SHOW   Displays the four components of a quaternion (array).
% Synonym for displayall(q).

% We have to duplicate the code here, otherwise when we pass the
% argument to show, show outputs q = and not the name of the original
% argument as we require.

% Note, there is no easy way to output a quaternion array in the
% same format as a complex array, therefore we resort to displaying
% the s, x, y, z components as real arrays.
