Derivative of positive linear transfer function
dA_dN = dposlin(N,A)
dposlin is the derivative function for poslin.
dposlin(N,A) takes two arguments, and returns the S x Q derivative dA/dN.
Here we define the net input N for a layer of 3 poslin neurons.
N = [0.1; 0.8; -0.7];We calculate the layer's output A with
poslin and then the derivative of A with respect to N.
A = poslin(N) dA_dN = dposlin(N,A)The derivative of
poslin is calculated as follows:
d = 1, if 0 <= n; 0, Otherwise..
