c8lib, a FORTRAN77 code which implements certain elementary functions for "C8" or double precision complex variables.
The symbol "C8" is used to suggest a double precision complex variable. Here the 8 indicates that the underlying pair of real numbers each use 8 bytes of storage.
The code contains routines that operate on scalars, vectors or doubly dimensioned arrays of C8's. A vector of C8's is denoted a C8VEC, and a doubly dimensioned array is a C8MAT.
The computer code and data files described and made available on this web page are distributed under the GNU LGPL license.
c8lib is available in a C version and a C++ version and a Fortran90 version and a MATLAB version and an Octave version and a Python version.
