SAVE	Save workspace variables on disk.
  	SAVE fname saves all workspace variables to the binary "MAT-file"
    	named fname.mat. The data may be retrieved with LOAD. Omitting the
    	filename causes SAVE to use the default filename "matlab.mat".
 
  	SAVE fname X  saves only X.
  	SAVE fname X Y Z  saves X, Y, and Z.
 
  	SAVE fname X Y Z  -ascii  uses 8-digit ASCII form instead of binary.
  	SAVE fname X Y Z  -ascii -double  uses 16-digit ASCII form.
  	SAVE fname X Y Z  -ascii -double -tabs  delimits with tabs.
 
    	If fname is "stdio", SAVE sends the data to standard output.
 
 	The binary formats used in MAT-files depend upon the size and type of
 	each matrix.  Small matrices and matrices with any noninteger entries
 	are saved in floating point format requiring 8 bytes per real element.  
 	Large, integer matrices may be saved in compact formats requiring
 	only 1, 2 or 4 bytes per element.  See the External Interface Library
 	for more details, including C and Fortran routines to read and write
 	MAT-files from external programs.
