The Matlab work

I do not know how to write the 'candy.CandyRank = '

% Read in and setup candy

% CHANGE HERE: Make sure this is your function and your data file

% CHANGE HERE: Put your code to calculate rank scores here

%% The code to do the checking

% Basically, call your function many, many times and see if it creates the

% same probability/rank values

candyPicked = zeros( size( candy.CandyRank ) );

%% CHANGE HERE: change the function MyPickCandy

% See instructions in MyPickCandy

picked = MyPickCandy( candy.CandyRank );

% Record which one was picked

candyPicked( picked ) = candyPicked( picked ) + 1;

end

% Normalize and set to same range of values as rank

candyPicked = sum( candy.CandyRank ) * candyPicked / sum( candyPicked );

%% CHECK HERE: The current version of MyPickCandy should

% produce roughly equal numbers (i.e., something like 3.1 2.9 3.05)

% Once MyPickCandy is correct these two arrays should be

% fairly similar (i.e., something like 3 2 4 and 3.10 1.9 4.1)
