MATLAB: How to compare two arrays

for loop

A=[
9.9090    8.3211  9.5763
9.7926    8.2055  9.4335
9.3428    7.7533  8.8443]
COMPARED TO
B=[
7.9   9.5    9.5
8.7   10.3   10.3
9.5   11.1   11.1
10.3  11.9   11.9
11.1  12.7   12.7
11.9  14.3   14.3]
i need code that compares each row of A with each row of B
choosing the very next value from B for each element in A
elaboration:-
first element in A is 9.9090 comparing it to first row in B
7.9 is less so rejected
8.7 is less so rejected
9.5 is less so rejected
10.3 is more so acceped
result= 
10.3   9.5  10.3
10.3   9.5  9.5
9.5    9.5  9.5

Best Answer

O=zeros(size(A));
for i=1:size(A,2)
  O(:,i)=interp1(B(:,i),B(:,i),A(:,i),'next','extrap');
 end
