// Based on the Python example here: https://en.wikipedia.org/wiki/Softmax_function
void Main()

	var z = new[] { 1.0, 2.0, 3.0, 4.0, 1.0, 2.0, 3.0 };

	var z_exp = z.Select(Math.Exp);
	// [2.72, 7.39, 20.09, 54.6, 2.72, 7.39, 20.09]

	var sum_z_exp = z_exp.Sum();
	// 114.98

	var softmax = z_exp.Select(i => i / sum_z_exp);
