Calculate oscillatory integrals using Julia
using ApproxFun,OscillatoryIntegrals
fourier(Fun(x->cos(x^2), 1..2), 10000.5)calculates the integral of cos(x^2)*exp(im*10000.5*x) over [1,2]
fourier(Fun(sech,Laurent(PeriodicLine())), 10.5)calcules the integral of sech(x)*exp(im*10.5*x) over the real line
