Title of program: NULLIJN Catalogue Id: ACYL_v1_0 Nature of problem When an algorithm for a function f of two variables, for instance a dispersion function f(w,k) or a potential V(r,z) is known, the program calculates and plots the zero curves, thus giving a graphical representation of an implicitly defined function. One of the variables may be complex. Versions of this program held in the CPC repository in Mendeley Data ACYL_v1_0; NULLIJN; 10.1016/0010-4655(78)90066-8 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
