Code Help for Matrix creation

Hello.

I have two matrices. 1st order is 61312*2 (two columns i.e. origin and destination, values ranges from 1 to 81 in both columns). 2nd matrix is 81*81 (include length between origin and destination)

Now I need to create a matrix having order 61312*3 i.e origin*destination*length, i.e. to write a code which take the value from 2nd matrix (length) for their respective values in 1st matrix.

Kindly let me know how should I proceed.

Can you give a small example. Also, what does this have to to with the Coder product? Do you need to translate this into C to embed it in silicon or something?

A = (61312x2 matrix)
B = (81x81 matrix)
C = [A B(A(:,1)+81*(A(:,2)-1))]; % 3rd column uses linear indexing into B

I've accepted the answer already. However if it is not the correct method, kindly let me know how to accept officially I will do that too :).
