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: h_zeros.m
    path of file: ./repos/d2d/arFramework3/ThirdParty/StrucID/adimat/opt_sp_derivclass
    
    the code of the file until where you have to start completion: function gz=h_zeros(varargin)

    
function gz=h_zeros(varargin)
%H_ZEROS Create a hessian object containing all zeros.
%   H_ZEROS(N) creates a Hessian object with number of directional derivatives
%              many N-by-N matrices of zeros.
%   H_ZEROS(M,N) or H_ZEROS([M,N]) creates a Hessian with n.o.d.d.
%               many M-by-N matrices of zeros.
%   H_ZEROS(M,N,P,...) or H_ZEROS([M N P ...]) creates a Hessian with n.o.d.d.
%               many M-by-N-by-P-by-... arrays of zeros.
