(copy of Prob. 963)

Given a 2-d matrix, remove the row average from each row. Your solution MUST be vectorized. The solution will be tested for accuracy AND speed. Any for loops will make the solution too slow to pass the speed test.

Example:

a = [ 1 2 ; 3 5 ];
b = remove_average_vectorized(a);
% b is [ -0.5 0.5 ; -1 1 ];
Solve
