Dear All,

 I am looking for a numerical integration routine (preferably in Fortran)
to integrate a function, which is only numerically defined. The numerical
values are equally spaced. I tried the trapezoid rule based numerical
recipe code. However, my (numerically defined) function has singularity (it
is like exp(-x)/x)) and the numerical recipe routine although works,
generally speaking, is not working for my case.

I would greatly appreciate if you suggest any routine which can do this
kind of integration.

thanks,
