+% function [x,check] = solve1(func,x,j1,j2,jacobian_flag,varargin)
+% Solves systems of non linear equations of several variables
+%
+% INPUTS
+%    func:            name of the function to be solved
+%    x:               guess values
+%    j1:              equations index for which the model is solved
+%    j2:              unknown variables index
+%    jacobian_flag=1: jacobian given by the 'func' function
+%    jacobian_flag=0: jacobian obtained numerically
+%    varargin:        list of arguments following jacobian_flag
+%    
+% OUTPUTS
+%    x:               results
