SAVEAS Save Figure or model to desired output format.
SAVEAS(H,'FILENAME')
Will save the Figure or model with handle H to file called FILENAME.
The format of the file is determined from the extension of FILENAME.
SAVEAS(H,'FILENAME','FORMAT')
Will save the Figure or model with handle H to file called FILENAME.
in the format specified by FORMAT. FORMAT can be the same values as
extensions of FILENAME. The FILENAME extension does not have to be
the same as FORMAT. Given FORMAT overrides FILENAME extension.
Valid options for FORMAT are:
'fig' - save figure to a single binary FIG-file. Reload using OPEN.
'm' - save figure to binary FIG-file, and produce callable
M-file for reload.
'mfig' - same as M.
'mmat' - save figure to callable M-file as series of creation commands
with param-value pair arguments. Large data is saved to MAT-file.
Note: MMAT Does not support some newer graphics features. Use
this format only when code inspection is the primary goal.
FIG-files support all features, and load more quickly.
Allowable options also include devices allowed by PRINT.
Examples:
Write current figure to MATLAB fig file
saveas(gcf, 'output', 'fig')
Write current figure to windows bitmap file
saveas(gcf, 'output', 'bmp')
