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: processFilenames.m
    path of file: ./repos/jidt/demos/octave/FlockingAnalysis
    
    the code of the file until where you have to start completion: function fileCellArray = processFilenames(fileList)
%
% Turns the fileList from the properties file (usually properties.files) into a cell array of file names. The fileList can be either:
% a. a cell array of file names, e.g.: {'file1.xlsx', 'file2.xlsx'}
% b. a call to ls or ls with an argument, e.g. ls('*.xlsx')
% c. a space or tab separated character row vector of file names
% d. a character matrix of filenames (each filename on a separate row)
