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.
