function varargout = padsiz(pad, varargin)
% DESCRIPTION [a,b,...] = padsiz(pad,a,b,...)
%  Will extend dimensions of
%  each input argument to maximum 
%  size of the other arguments.
% INPUT
%  pad --       Nonfilled areas are padded with this value.
%  varargin --  Matrices of any size
% OUTPUT
%  The result is matrices of the same size.
%  The nonfilled areas are padded with pad.
% TRY
%  [a, b] = padsiz(NaN, ones(1,2), ones(2,1))
