functions

core.Global.functions(name, network=None)

Allows to access a global function declared with add_function and use it from Python using arrays after compilation.

The name of the function is not added to the global namespace to avoid overloading.

add_function("logistic(x) = 1. / (1. + exp(-x))") 

ann.compile()  

result = functions('logistic')([0., 1., 2., 3., 4.])

Only lists or 1D Numpy arrays can be passed as arguments, not single values nor multidimensional arrays.

When passing several arguments, make sure they have the same size.

Parameters
