You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: spm_print.m
    path of file: ./repos/malini/Codes/deconvolution - model/spm8
    
    the code of the file until where you have to start completion: function spm_print(varargin)
% Print the Graphics window
% FORMAT spm_print
% Print the default window to the default output file.
% FORMAT spm_print(filename)
% Print the default window to the specified output file.
% FORMAT spm_print('',figurename)
% Print the window with the specified name to the default output file.
% FORMAT spm_print(filename,figurename)
% Print the window with the specified name to the specified output file.
% FORMAT spm_print('',figurehandle)
% Print the figure with the specified handle to the default output file.
% FORMAT spm_print(filename,figurehandle)
% Print the figure with the specified handle to the specified output file.
% FORMAT spm_print(job)
% Run a batch print job, print the specified window to the specified
% output file.
