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: PeakDetection.m
    path of file: ./repos/chromatography/Methods/Integration
    
    the code of the file until where you have to start completion: % Method: PeakDetection
%  -Find peaks and peak boundary points
%
% Syntax
%   peaks = PeakDetection(y)
%   peaks = PeakDetection(x, y)
%   peaks = PeakDetection(x, y, 'OptionName', optionvalue...)
%
% Input
%   x        : array
%   y        : array or matrix
%
% Options
%   'center' : value or array
%   'width'  : value or array
%
% Description
%   x        : time values
%   y        : intensity values
%   'cent
    
function varargout = PeakDetection(varargin)

% Check input
[x, y, options] = parse(varargin);

% Pre-allocate memory
empty = zeros(2, length(y(1,:)));

% Initialize peak data
peak.center = empty;
peak.height = empty;
peak.width = empty;
peak.a = empty;
peak.b = empty;
peak.alpha = empty;

% Determine peak locations
for i = 1:length(y(1,:))
    
    % Set variables
    if length(options.center) == length(y(1,:))
        center = options.center(i);
    else
        center = options.center(1);
    end
