Answer:
Here's a list of the different ways to do this ...
... using :
B = bsxfun(@rdivide,A,sum(A));
... using :
B = A./repmat(sum(A),size(A,1),1);
... using an (as suggested by ):
B = A./(ones(size(A,1),1)*sum(A));
... and using a for loop (as suggested by ):
B = A;columnSums = sum(B);for i = 1:numel(columnSums) B(:,i) = B(:,i)./columnSums(i);end
