问题
I have nine open figures in matlab (generated by another function) and I want to print them all to file. Does anyone know how to grab the handles of all open figures in MATLAB?
I know about gcf but it doesn\'t seem to do what I want.
回答1:
There are a few ways to do this. One way to do this is to get all the children of the root object (represented in prior versions by the handle 0):
figHandles = get(groot, 'Children'); % Since version R2014b
figHandles = get(0, 'Children'); % Earlier versions
Or you could use the function findobj:
figHandles = findobj('Type', 'figure');
If any of the figures have hidden handles, you can instead use the function findall:
figHandles = findall(groot, 'Type', 'figure'); % Since version R2014b
figHandles = findall(0, 'Type', 'figure'); % Earlier versions

One of the best things to do is to NOT need to look for the handles. When you create each figure, capture its handle.
h(1) = figure;
h(2) = figure;
...
As one of the developers here told me:
They are called handles, because you are supposed to hold on to them
回答3:
I think findall should work
handles=findall(0,'type','figure')

You've get fine answers for the handles mass. But another tip for the original question- print all the figures to file: you can use publish option, without dealing with figrues or handles.
