Is there any article that help me study automorphisms of nilpotent groups of class two with cyclic center? 
In "[Odd order nilpotent groups of class two with cyclic centre](https://doi.org/10.1017/S1446788700016724), Y. K. Leong (1974)" there is a presentation of nilpotent groups of class two with cyclic center. How can I find the structure of automorphisms of these groups by using this presentations?
