用save保存，load读取，可以多种格式，见save的在线帮助。
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.
SAVE FILENAME -REGEXP PAT1 PAT2 can be used to save all variables
matching the specified patterns using regular expressions. For more
information on using regular expressions, type "doc regexp" at the
command prompt.
SAVE FILENAME -STRUCT S saves the fields of the scalar structure S as
individual variables within the file FILENAME.
SAVE FILENAME -STRUCT S X Y Z saves the fields S.X, S.Y and S.Z to
FILENAME as individual variables X, Y and Z.
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 ... -V6 saves a MAT-file that MATLAB 6 can LOAD.
SAVE ... -V4 saves a MAT-file that MATLAB 4 can LOAD.
SAVE ... -APPEND adds the variables to an existing file (MAT-file
only).
By default, MAT-files created with SAVE are compressed and char arrays are
encoded using Unicode. These MAT-files cannot be loaded into versions of
MATLAB prior to MATLAB 7.0. The -V6 option disables these features and
allows saved MAT-files to load into older versions of MATLAB. To disable
these features by default, modify the settings in the General->MAT-Files
preferences panel, accessible via the File->Preferences menu item. With
compression enabled, saving data that does not compress well takes
longer. In this case, the -V6 option may be preferable.
When using the -V4 option, variables that are 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.
Examples for pattern matching:
save fname a* % Save variables starting with "a"
save fname -regexp ^b\d{3}$ % Save variables starting with "b" and
% followed by 3 digits
save fname -regexp \d % Save variables containing any digits |
