Integration

The two files LoadAndUseIntegral.nb and Integral.m are a pair of Mathematica notebooks which implement the calculation of comprehensive integrals with Kahanian constants. The theory behind the computation is described in the paper "Integrals of functions containing parameters" by Corless, Jeffrey and Stoutemyer, The Mathematical Gazette, November 2020. A PDF of the paper is available below. The file LoadAndUseIntegral.nb will load the second file (as its name suggests) and provide an interface to the calculation. The file KahanianIntegration.nb only contains the same instructions as this description and is included here to intercept searches based on earlier published references.
