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: FemapDataBlock450.m
    path of file: ./repos/NASTRAN_CoFE/nastran_cofe/hdf5_output_processors
    
    the code of the file until where you have to start completion: % Class for FEMAP Neutral File Data Block 450 - Output Sets
% Anthony Ricciardi
%
classdef FemapDataBlock450 < FemapDataBlock
    
    properties
        ID % [int] ID of output set
        title % [max 79 char] Output Set title
        anal_type % [int] Type of analysis (0=Unknown, 1=Static, 2=Modes, 3=Transient, 4=Frequency Response, 5=Response Spectrum, 6=Random, 7=Linear Buckling, 8=Design Opt, 9=Explicit, 10=Nonlinear Static, 11=Nonlinear Buckling, 12=Nonlinear Transient, 19=Comp Fluid Dynamics, 20=Steady State Heat Transfer, 21=Transient Heat), 22=Advanced Nonlinear Static, 23=Advanced Nonlinear Transient, 24=Advanced Nonlinear Explicit, 25=Static Aeroelasticity, 26=Aerodynamic Flutter)
