% @deftypefn {Function File} {@var{b} =} unwrap (@var{a}, @var{tol}, @var{dim})
%
% Unwrap radian phases by adding multiples of 2*pi as appropriate to
% remove jumps greater than @var{tol}. @var{tol} defaults to pi.
%
% Unwrap will unwrap along the first non-singleton dimension of
% @var{a}, unless the optional argument @var{dim} is given, in
% which case the data will be unwrapped along this dimension
