Graduate Memory issues in numerical integration of oscillatory function
Your approach looks very interesting, thank you. I'm trying to understand it. Are you using the periodicity property of the exp(iωt) function? In the case A(t) = 1, the integral will have the form: $$\int_{0}^{\infty }e^{e^{i\omega t}}=\sum_{n=0}^N \int_{0}^{2\pi/\omega}e^{e^{i\omega t}}$$ Is...- cyberpotato

Graduate Memory issues in numerical integration of oscillatory function
Hello! I need to numerically integrate a frequently oscillating, decaying complex function over the interval from 0 to infinity, which is continuous. For brevity, I provide the general integral view $$\int_{0}^{\infty} A(t)e^{e^{iw't}}dt$$. I'm using Python libraries for this task...- cyberpotato
