save函数编程编辑
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'.
SAVE FILENAME X saves only X.
