How can I store the properties of a figure in MATLAB, then reset them at a later time?

I want to store the properties of a figure in order to reset the figure's current configuration at a later time. For example, I would like to read my figure's properties using:

line

props = get(gcf);

Then, after having made some changes, I would like to reset all properties using:

fnames = fieldnames(props);

for n = 1:length(fnames)

      set(gcf,fnames{n},props.(fnames{n}))

end

However, I obtain the following error:

 ??? Error using ==> set

 Attempt to modify read-only figure property: 'BeingDeleted'.

The GET function returns properties that are read-only and cannot be set using the SET function.

The best method for storing a figure's properties, then resetting them at a later time, is to use the SAVEAS function to save the figure as a FIG-file.

saveas(gca, 'foo', 'fig');

Then, you can load this figure using the OPEN function:

open('foo.fig');

However, if you would like to store the properties in a variable, you can avoid the read-only properties when resetting the figure. The read-only properties of a figure are specified as:

readonly = {'BeingDeleted','CurrentCharacter','CurrentObject','FixedColors','Type'};

Then, the figure properties can be reset using:

props = rmfield(props, readonly);

fnames = fieldnames(props);

for n = 1:length(fnames)

      set(gcf,fnames{n},props.(fnames{n}))

end
