Hi My two cents:
1. high-level solution: use my piece of software wasora from www.seamplex.com/wasora that inputs a human-friendly input file and interfaces with GSL. For example, this file https://bitbucket.org/seamplex/wasora/src/master/examples/solve.was solves the system of equations y = exp(-f(z)*x) x = integral(f(z'), z', 0, z) 2 = x+y+z where f(z) is a pointwise-defined function like $ wasora solve.was x = 0.319603 y = 0.784170 z = 0.896227 $ 2. low-level solution: see https://bitbucket.org/seamplex/wasora/src/master/src/multiroot.c Regards -- jeremy theler www.seamplex.com On Sat, 2017-07-08 at 08:57 +0300, Sergey Shcherbina wrote: > Hi! > > I am beginner in this excellent scientific area - GSL and I search > now a C code > for solving the system of nonlinear equations.
