You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: TransitionPath_Case1_FHorz_e_shooting.m
    path of file: ./repos/VFIToolkit-matlab/TransitionPaths/FHorz
    
    the code of the file until where you have to start completion: function PricePathOld=TransitionPath_Case1_FHorz_e_shooting(PricePathOld, PricePathNames, PricePathSizeVec, ParamPath, ParamPathNames, ParamPathSizeVec, T, V_final, AgentDist_initial, n_d, n_a, n_z, n_e, N_j, d_grid,a_grid,z_gridvals
    
function and Optimal policy function at each step. Since we won't need to keep the value
    % functions for anything later we just store the next period one in Vnext, and the current period one to be calculated in V
    V=V_final;

    % % disp('HereFinal')
    % % V_final(1:100)

    for ttr=1:T-1 %so t=T-i

        for kk=1:length(PricePathNames)
            Parameters.(PricePathNames{kk})=PricePathOld(T-ttr,PricePathSizeVec(1,kk):PricePathSizeVec(2,kk));
        end
