Save graphics object hierarchy to file
Note: hgsave is not recommended. Use savefig instead.
hgsave(h,'filename') saves the objects identified by the array of handles h to a file named filename. If you do not specify an extension for filename, then the extension .fig is appended. If h is a vector, none of the handles in h may be ancestors or descendents of any other handles in h.
hgsave(...,'-v7.3') saves the FIG-file in a format that can be loaded only by MATLAB versions 7.3 and above. This format, based on HDF5 files, is intended for saving FIG-files larger than 2 GB.
You can make -v6 or -v7.3 your default format for saving MAT-files and FIG-files by setting a preference, which will eliminate the need to specify the flag each time you save. See MAT-Files Preferences in the MATLAB Desktop Tools and Development Environment documentation.
When creating a figure you want to save and use in a MATLAB version prior to MATLAB 7, use the 'v6' option with the plotting function and the '-v6' option for hgsave. Check the reference page for the plotting function you are using for more information.
In MATLAB release R2014b or later, you cannot open a save FIG-file in earlier versions of MATLAB. Use savefig to save figures that are compatible with earlier versions of MATLAB.
Use the File > Export Setup dialog. Use Edit > Copy Figure to copy the figure's content to the system clipboard. Fore details, see How to Print or Export.
