function putsolu(mesh, filename, format, varargin)
% PUTSOLU saves the current finite element solution to a file with
% designated file name and format. 
% 
% USAGE
%    putsolu(mesh, filename, format, varargin)
%
% INPUT 
%       mesh:  current mesh structure
%   filename:  file name you want to use to save mesh and solution
%     format:  picture format 
%              supported format includes ps, eps, ps2, eps2, jpeg, png,
%              etc (see the help of MATLAB command print), default format
%              is "epsc".
%   varargin:  view angles and other optional parameters
%
% Examples
%    putsolu(mesh)
%    putsolu(mesh, 'savedsolu', 'png')
%    putsolu(mesh, 'savedsolu', 'eps', 30, 10, 'tiff', 'r300')
