Hi Friedrich and everybody else,
Thank you for your reply.
I think I am not getting everything, but in my understanding,
the object which I create is not a Figure or an Axis, it is an
AxesImage. gca() or gcf() return errors indeed.
Therefore, I cannot use attributes which are specific to Figures
and Axes.
Would there be a reason for the class AxesImage to handle
very few attributes? Is this class not so popular? :p
Best,
Marianne
