MATLAB: Combination function using ndgrid

Question

Hello,

I want to build a function which use ndgrid.

My function is

function [ varargout ] = comb( varargin )
[varargout]=ndgrid(varargin)
varargout=varargout(:);
disp([varargout])
end

My varargout are x1 x2 x3 and varargin are a,b,c where a=[1 2], b=[2 3] and c=[1 4]. Expected results are

       1     2     1
       2     2     1
       1     3     1
       2     3     1
       1     2     4
       2     2     4
       1     3     4
       2     3     4

but it seems like ndgrid doesn't work. What can i do? In command window works fine but as a function where I can put more varargins something is wrong.

Answer 1

function varargout = comb(varargin)
   varargout = cell(1, nargout);
   [varargout{:}] = ndgrid(varargin{:};  %distribute to varargout
   varargout = cellfun(@(m) reshape(m, [], 1), varargout, 'UniformOutput', false); %reshape into columns
end
