c4lib, a Fortran77 code which implements certain elementary functions for single precision complex variables.
The symbol "C4" is used to suggest a single precision complex variable. Here the 4 indicates that the underlying pair of real numbers each use 4 bytes of storage.
The code contains routines that operate on scalars, vectors or doubly dimensioned arrays of C4's. A vector of C4's is denoted a C4VEC, and a doubly dimensioned array is a C4MAT.
