    I am doing a research degree in optical fields and ended up with the following integral in my math model. can you suggest any method to evaluate this integral please. Thanks in advance

    ∫(j(x) *e^(ax^2+ibx^2) dx

    J --> zero order bessel function
    i--. complex
    a & b --> constants

    If the limits are from 0 to infinity it can be easily evaluated using Webers double integral.
    for other limits I dont think a close form exists.
    Check: Watson: A treatise on the theory of Bessel functions
    for more details
