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: ipctb_spm_platform.m
    path of file: ./repos/bspm/thirdparty/MIALAB/gipc1d/ipctb_spm5_files
    
    the code of the file until where you have to start completion: function varargout=ipctb_spm_platform(varargin)
% Platform specific configuration parameters for SPM
%
% FORMAT ans = ipctb_spm_platform(arg)
% arg  - optional string argument, can be
%        - 'bigend'  - return whether this architecture is bigendian
%                      - Inf - is not IEEE floating point
%                      - 0   - is little end
%                      - 1   - big end
%        - 'filesys' - type of filesystem
%                      - 'unx' - UNIX
%
