function d1 = bksupk(ny,fid,jcf,icc1)
% function d1 = bksupk(ny,fid,jcf,icc1)
% Solves deterministic models recursively by backsubstitution for k leads/lags
%
% INPUTS
% ny: number of endogenous variables
% fid: saves the elements above the diagonal
% jcf: variables index forward
% icc1: jacobian column forward
%
% OUTPUTS
% d1: vector of backsubstitution results
%
% SPECIAL REQUIREMENTS
% none
