Given a matrix with an even number of columns, n, return a 1-by-2 row vector where the first element is the mean of all the elements in the first n/2 columns, and the second element is the mean of all the elements in the second n/2 columns.
For example
A 3-by-4 matrix. The first two columns are blue, the second two are orange. The mean of the 6 blue elements is calculated. The mean of the 6 orange elements is calculated. The result is a 2-element row vector containing these two means.
A = [3 4 4 3;
1 2 5 3;
1 1 4 5];
m = halfmeans(A)
m =
2 4
(2 = mean of [3,4,1,2,1,1], 4 = mean of [4,3,5,3,4,5])
