          CPQR79-C
 
          RPZERO-S  Find the zeros of a polynomial with real coefficients.
          CPZERO-C
 
F1A1B.  Complex coefficients
 
          CPQR79-C  Find the zeros of a polynomial with complex coefficients.
          RPQR79-S
 
          CPZERO-C  Find the zeros of a polynomial with complex coefficients.
          RPZERO-S
 
F1B.  General (no smoothness assumed)
 
          FZERO-S   Search for a zero of a function F(X) in a given interval
          DFZERO-D  (B,C).  It is designed primarily for problems where F(B)
                    and F(C) have opposite signs.
 
F2.  System of equations
F2A.  Smooth
 
          SNSQ-S    Find a zero of a system of a N nonlinear functions in N
          DNSQ-D    variables by a modification of the Powell hybrid method.
 
          SNSQE-S   An easy-to-use code to find a zero of a system of N
          DNSQE-D   nonlinear functions in N variables by a modification of
                    the Powell hybrid method.
 
          SOS-S     Solve a square system of nonlinear equations.
          DSOS-D
 
F3.  Service routines (e.g., check user-supplied derivatives)
 
          CHKDER-S  Check the gradients of M nonlinear functions in N
          DCKDER-D  variables, evaluated at a point X, for consistency
                    with the functions themselves.
