Let M be a matrix whose entries are positive integers. What does the following function do? function v=Summat (M) [mn]=size (M); v=zeros (m, 1); for i=1:m for j=1:n if mod (M(i, j),2)==0 v(i)=v(1) +M(i, j); end end end Creates a vector whose ith entry is the sum of the odd elements of the ith row of M Creates a vector whose ith entry is the sum of the even elements of the ith column of M Creates a vector whose ith entry is the sum of the odd elements of the ith column of M O Creates a vector whose ith entry is the sum of the even elements of the ith row of M
