% Get the dimensions of the image.
[rows columns] = size(binaryImage);
% Find the middle column
middleColumn = columns/2;
% Count the number of 1's in each half.
leftHalfOnes = nnz(binaryImage(:,1:middleColumn))
rightHalfOnes = nnz(binaryImage(:,middleColumn+1:end))

Did you look for it? Did you look up near the top of this page? There are blue letters that say "File Exchange" If you can't see it, then here it is: http://www.mathworks.com/matlabcentral/fileexchange/

If your image is logical, then you could easily do this using the function "nnz", which gives you the number of non-zeros a matrix. Alternatively, you could just sum each side of the image if the "white pixels" are 1's.
