Compare two matrices and find similar values

I have two matrices with 3 column each. I want to compare the rows, the first matrix is:

6  40  110
6  40  573
6  41  66
6  41  471
6  41  691
6  41  945
6  42  201
6  42  468...

and the second is:

6  40  79
6  40  179
6  40  279
6  40  379
6  40  479
6  40  579...

I want to compare the rows of these two matrices and find the closest values each other. Any suggestion?

What do you mean by closest values?

Please give the example of how the output should be for the above 2 matrices

[Michela Longhi]

such as: if

6  40  279 (from matrix 2)

is closet to

6  40  110 (from matrix 1)

or to

6  40  573 (from matrix 1)

and the answer is, obviously, 6 40 110

From my understanding,you want to find the closest matching row in matrix B for each of the rows in matrix A in terms of its values. Suppose, for the first row of matrix A [6 40 110] , the closest matching row in matrix B should be [6 40 79]. You can use the following:

[~,indx]=min(pdist2(B,A(i,:),'euclidean'));
result=B(indx,:);
result

where i= rowNumber of matrix A you want to find the match for. Similarly, for row 2 of matrix A [6 40 573], the closest matching row in matrix B should be [6 40 579].
