Programs for computing the logarithm of the gamma function, and the digamma function, for complex argument

Title of program: CLOGAM AND CDIGAM Catalogue Id: ACRG_v1_0 Nature of problem The gamma function, its logarithm, and its logarithmic derivative appear in a wide range of physical applications. We mention here only the Veneziano model and its generalizations in high-energy physics, and the Coulomb phase shift for complex energies.
