Hello everyone. I have a struct called temp which has 5 fields
I want to delete all the fields starting with 'fig' and 'ax'. The final output struct should look something like
I know that we can do it in a complex way using fieldnames and rmfield with multiple lines of code.
Is there any simple way to do this? Thanks in advance.

You do have to use fieldnames and rmfield indeed. It's only two lines and not complicated at all:
fns = fieldnames(temp);
temp = rmfield(temp, fns(startsWith(fns, {'fig', 'ax'})))
edit: However, note that if you're trying to remove all the graphics objects from your structure a more reliable method would be:
fns = fieldnames(temp);
temp = rmfield(temp, fns(cellfun(@(fn) ishghandle(temp.(fn)), fns)));
