CHECKDEN

A program to compute many functions dependent on the electron density ${\rho}(\bold r)$ from the results of ab initio molecular calculations is presented. The program allows the generation of different one-, two-, and three-dimensional grids for further graphical representation or numerical analysis. Other options like extracting separate atom contributions to the functions computed or locating maximum and minimum values are also implemented. A number of illustrative applications regarding different ${\rho}(\bold r)$-dependent functions are presented and the performance and portability of the program is discussed.
