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