PHYSICS AS A COMPUTATIONAL CODE
Between experimentally different situations, exist special physical interrelations. The corresponding observables of the compared processes may occur to be expressed by dissimilar mathematical expressions. Hence, numerical correspondences appear between different mathematical functions. To a large measure, the use of the presentday computer algebra packages removes the distinction between elementary and transcendental functions. Nevertheless, the software implementation of algorithms for computation of these functions retain some differences that may manifest themselves, e.g., in multiple recursions. In any case, the numerical likelihood of the different analytical expressions could be of interest for applications. Here we point at several examples of physically based interpolations.
