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.m
    path of file: ./repos/VFIToolkit-matlab/TransitionPaths/FHorz
    
    the code of the file until where you have to start completion: function PricePath=TransitionPath_Case1_FHorz(PricePathOld, ParamPath, T, V_final, AgentDist_init, n_d, n_a, n_z, N_j, pi_z, d_grid,a_grid,z_grid, ReturnFn, FnsToEvaluate, GeneralEqmEqns, Parameters, Discou
    
function 
        transpathoptions.pi_z_J_alt=permute(pi_z_J,[1,3,2]); % But is (j,z,z') for agent dist with fastOLG [note, this permute is off the previous one]
        if transpathoptions.zpathtrivial==0
            temp=transpathoptions.z_grid_J_T;
            transpathoptions=rmfield(transpathoptions,'z_grid_J_T');
            transpathoptions.z_gridvals_J_T=zeros(N_z,l_z,N_j,T,'gpuArray');
            for tt=1:T
                for jj=1:N_j
                    z_gridvals_J(:,:,jj,tt)=CreateGridvals(n_z,temp(:,jj,tt),1);
