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: fbCreate.m
    path of file: ./repos/MCITF/Code/MCITF/Feat/textons
    
    the code of the file until where you have to start completion: function [fb] = fbCreate(numOrient,startSigma,numScales,scaling,elong)
% function [fb] = fbCreate(numOrient,startSigma,numScales,scaling,elong)

    
function [fb] = fbCreate(numOrient,startSigma,numScales,scaling,elong)
% function [fb] = fbCreate(numOrient,startSigma,numScales,scaling,elong)
%
% Create a filterbank containing numOrient even and odd-symmetric
% filters and one center-surround filter at numScales scales.
%
% The even-symmetric filter is a Gaussian second derivative.
% The odd-symmetric filter is its Hilbert transform.

% See also oeFilter, csFilter, fbRun.
