Gaussian Integration

  1. Jun 4, 2003 #1
    I have some doubts about it..in fact when you want to calculate an integral numerically..i always use gaussian integration but what would happen if i use this technique to calculate:

    Int(0,1000)g(x)[f(x)]dx where [] means the floor function in fact it is a non-continuous function..would be gaussian integration valid in this case?...

    It would still be valid, but you'd be better off doing the integral separately for each interval between the jumps.
