    numerically integrate to infinity

    Thank you very much for your smart comment. Maybe you have missed that Matlab does have rules to calculate with infinity. So why not implement a numerical integration that takes on the value zero, if the function is numerically zero and infinity if it takes on nonzero equally signed values...
