Hi there,
I repeatedly received this error message while running the imregtform function. I wonder what can I do to solve it? It seems like nothing to do with my input data. But totally the problem in affine2d.empty().
Error using affine2d.empty
Abstract classes cannot be instantiated. Class 'affine2d' inherits abstract methods or properties but does not implement them. See the list of methods and
properties that 'affine2d' must implement if you do not intend the class to be abstract.
Error in imregtform>parseInputs (line 255)
parser.addParamValue('InitialTransformation',affine2d.empty(),@checkInitialTransformation);
Best,
Clover

Oh, you did override it.... Try renaming your class and file into something else

I have had this problem for a couple of months now. i'm glad this was posted just 48 hours ago!
the same goes for the pReLu layer and the maeRegressionLayer in the deep-learning toolbox
I didnt post a question, because I feel the matlab deep learning toolbox is still developing.
for search-indexing, i will paste the text message of this error:
Abstract classes cannot be instantiated. Class 'maeRegressionLayer' inherits abstract methods or properties but does not implement them. Use meta.abstractDetails to see the list of methods and properties that 'maeRegressionLayer' must implement if you do not intend the class to be abstract.
Abstract classes cannot be instantiated. Class 'preluLayer' inherits abstract methods or properties but does not implement them. Use meta.abstractDetails to see the list of methods and properties that 'preluLayer' must implement if you do not intend the class to be abstract.
