[Help-gsl] QAWS & conditional IF / ELSE definition in integrand function

[Mátyás Benke]

Hi guys,

I have a quick question regarding the QAWS algorithm. 
Does QAWS allow you to define the integrand function using IF / ELSE 
conditions. 
For example, will it work in the following way? 

double f (double x, void * params) 
{
       double alpha = *(double *) params;
       double f = log(alpha*x) / sqrt(x);
       if (x > 0.0)
           return f;
       else
           return 0.0;
}Cheers, Matyas
