function varargout = map(fun, varargin)
% Y = map(fun, C)
% Wrapper around cellfun. Takes function handle fun and cell array
% C and returns a new cell array that contains the result of
% applying fun to each element of C.
% If fun takes N arguments, map must be passed N cell arrays
% corresponding to those N arguments:
% Y = map(fun, C1, C2, C3, ...);
% Each input cell array must have the same size.
% Similarly, map can handle functions that have multiple outputs. If
% called like this:
% [Y1, Y2, Y3, ...] = map(fun, C)
% Y1, Y2, ... will each be a cell array containing the analogous
% outputs of fun.
