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_PType.m
    path of file: ./repos/VFIToolkit-matlab/TransitionPaths/FHorz/PType
    
    the code of the file until where you have to start completion: function PricePath=TransitionPath_Case1_FHorz_PType(PricePathOld, ParamPath, T, V_final, StationaryDist_init, n_d, n_a, n_z, N_j, Names_i, d_grid,a_grid,z_grid, pi_z, ReturnFn, FnsToEvaluate, GeneralEqmEq
    
function (that depends on age, and possibly on permanent
    % type), or they could be a structure. Only in the case where they are
    % a structure is there a need to take just a specific part and send
    % only that to the 'non-PType' version of the command.
    
    % Start with those that determine whether the current permanent type is finite or
    % infinite horizon, and whether it is Case 1 or Case 2
    % Figure out which case is relevant to the current PType. This is done
    % using N_j which for the current type will evaluate to 'Inf' if it is
    % infinite horizon and a finite number for any other finite horizon.
    % First, check if it is a structure, and otherwise just get the
    % relevant value.
    
    % Horizon is determined via N_j
    if isstruct(N_j)
        PTypeStructure.(iistr).N_j=N_j.(Names_i{ii});
    elseif isscalar(N_j)
        PTypeStructure.(iistr).N_j=N_j;
    else
        PTypeStructure.(iistr).N_j=N_j(ii);
    end
