Error using matlab.graphics.axis.Axes/set
There is no String property on the Axes class.

image objects don't have either a String or a Title property. The axes in which image objects are contained don't have a String property either, but you can give them a title using the title function.
To ensure you're adding the title on the correct axes use ancestor on the image handle.
h = image(magic(16));
ax = ancestor(h, 'axes');
title(ax, 'title for magic image')
