is there a substraction operation between Deep Learning layers?

Hi guys,

I'm trying to build a DeepLearning network which contains a subtraction operation between two layers, and I can't find a way to do that while MATLAB has just an addition operation (additionLayer)?

for more clarification, the equation below discribes the step that I should do:

C = X - AvgPooling(X)

any suggestions guys?

I think maybe you can define a custom layer that implement a layer multiplicated by -1, then use additionLayer to get what you want.
