By this:
impoly > Generate Data > function createfigure1
Do you mean after calling impoly, you go into the figure window and select “Generate Code”? Which will create a function createfigure – but this has nothing to do with impoly.
There are a couple of ways you can extract the ROI.
After choosing the area with impoly, before closing the figure:
BW = createMask(h);
Or you can extract the position with getPosition and then use roipoly.
