FEE method

In mathematics, the FEE method is the method of fast summation of series of a special form. It was constructed in 1990 by and was called FEE – fast E-function evaluation – because it makes fast computations of the Siegel -functions possible, in particular of . A class of functions, which are 'similar to the exponential function' was given the name 'E-functions' by Siegel. Among these functions are such special functions as the hypergeometric function, cylinder, spherical functions and so on. Using the FEE, it is possible to prove the following theorem:
