%SAVE Save workspace variables to disk. 
%  SAVE FILENAME saves all workspace variables to the binary "MAT-file"
%  named FILENAME.mat.  The data may be retrieved with LOAD.  If FILENAME
%  has no extension, .mat is assumed.  
%
%  SAVE, by itself, creates the binary "MAT-file" named 'matlab.mat'.  It is
%  an error if 'matlab.mat' is not writable.
%
%  SAVE FILENAME X  saves only X.
%  SAVE FILENAME X Y Z  saves X, Y, and Z. The wildcard '*' can be used to
%  save only those variables that match a pattern.
%
%  ASCII Options:
%  SAVE ...  -ASCII  uses 8-digit ASCII form instead of binary regardless
%                    of file extension.
%  SAVE ...  -ASCII -DOUBLE  uses 16-digit ASCII form.
%  SAVE ...  -ASCII -TABS  delimits with tabs.
%  SAVE ...  -ASCII -DOUBLE -TABS  16-digit, tab delimited.
%
%  MAT Options:
%  SAVE ...  -MAT     saves in MAT format regardless of extension.
%  SAVE ...  -V4      saves a MAT-file that MATLAB 4 can LOAD.
%  SAVE ...  -APPEND  adds the variables to an existing file (MAT-file only).
%
%  When using the -V4 option, variables that incompatible with MATLAB 4 are
%  not saved to the MAT-file. For example, ND arrays, structs, cells, etc.
%  cannot be saved to a MATLAB 4 MAT-file. Also, variables with names that
%  are longer than 19 characters cannot be saved to a MATLAB 4 MAT-file.
%
%
%  Use the functional form of SAVE, such as SAVE('filename','var1','var2'),
%  when the filename or variable names are stored in strings.
