Would any one please suggest the best numerical method for integrating complicated integrands and singular functions? I find that Gauss quadratures are suggested by many references but I can't find a method to obtain the abscissas and weights for a general function.

My book "Numerical Recipes for C" has a chapter on integration and in particular a paragraph on the integration of improper integrals. As I understand it, you need to find out where the singularities are, so you can calculate openended integrations of the sections between the singularities.
