scipy.maxentropy.arrayexpcomplex

scipy.maxentropy.arrayexpcomplex(x)

Returns the elementwise antilog of the vector x. We try to exponentiate with numpy.exp() and, if that fails, with python’s math.exp(). numpy.exp() is about 10 times faster but throws an OverflowError exception for numerical underflow (e.g. exp(-800), whereas python’s math.exp() just returns zero, which is much more helpful.
