print(filename)
or, alternately,
print filename
where filename is the (string) filename of the destined file.  The current
fig is then saved to the output file using a format that is determined
by the extension of the filename.  The exact output formats may vary on
different platforms, but generally speaking, the following extensions
should be supported cross-platform:
jpg, jpeg  --  JPEG file 
 pdf -- Portable Document Format file
 png -- Portable Net Graphics file
 svg -- Scalable Vector Graphics file
 
--> x = linspace(-1,1);
--> y = cos(5*pi*x);
--> plot(x,y,'r-');
--> print('printfig1.jpg')
--> print('printfig1.png')
which creates two plots printfig1.png, which is a Portable
Net Graphics file, and printfig1.jpg which is a JPEG file.
