I’m trying to write the sigmoid function as below, but did not work: function sigmoid(z::Array) return 1.0 ./ (1.0 + exp(-z)) end; Knowing that the below is working fine, but I’m looking for a short way to write it: function sigmoid(z::Array) sig = [] for (index, value) in enumerate(z…

Instead of defining sigmoid(z::Array) define sigmoid(z::Real) and then use broadcasting to apply it to the elements of an array: sigmoid.(z) (note the dot, which indicates broadcasting) This is also the problem you’re facing in your OP. If you were to define sigmoid(z::Array), which (again) you sho…
