function [A,B,ys,info] = dynare_resolve(iv,ic,aux)
% function [A,B,ys,info] = dynare_resolve(iv,ic,aux)
% Computes the linear approximation and the matrices A and B of the
% transition equation
%
% INPUTS
% iv: selected variables (observed and state variables)
% ic: state variables position in the transition matrix columns
% aux: indices for auxiliary equations
%
% OUTPUTS
% A: matrix of predetermined variables effects in linear solution (ghx)
% B: matrix of shocks effects in linear solution (ghu)
% ys: steady state of original endogenous variables
% info=1: the model doesn't determine the current variables '...' uniquely
% info=2: MJDGGES returns the following error code'
% info=3: Blanchard Kahn conditions are not satisfied: no stable '...' equilibrium
% info=4: Blanchard Kahn conditions are not satisfied:'...' indeterminacy
% info=5: Blanchard Kahn conditions are not satisfied:'...' indeterminacy due to rank failure
% info=11: same as dr1 for dr_algo = 2
% info=20: can't find steady state info(2) contains sum of sqare residuals
% info=30: variance can't be computed
%
% SPECIAL REQUIREMENTS
% none
