Hello, I need to calculate the incomplete Bessel function. The form of this function is defined by the formula inf K (x,y) = int exp(-(xt+(y/t))) * (t**(n-1)) dt n 1 with x and y .gt. 0 and arbitrary n. More particularly, I have to evaluate this for n=0. Does anybody have any information on the availability of algorithm(s) for this. Thanks in advance. Isabelle Flamant
