I'm having some difficulty performing an array calculation. I would like to fill the contents of column 3 based on a specific formula using the contents of columns 1 and 2. I have some example code below.

% Example data.
column1data = [231.3 228.8 237.5 222.5]';
column2data = [107.5 121.3 108.8 111.3]';
% I want to create an addtional 3 columns so I end up with a 4 x 5 array.
% I first create a vector that is the same length as vectors 1 and 2.
lendata = length(column1data);
% I then create three additional vectors (columns) of zeros and join all together.
column3 = zeros(1, lendata)';
column4 = zeros(1, lendata)';
column5 = zeros(1, lendata)';
array = [column1data column2data column3 column4 column5];
