pls, help me with this

I have the following matrix:

Name_1 Name_2 ..... Name_n
23.5    25.8          29.6
24.5    85.5 ........ 59.2
.        .   ........  .

and so on. A matrix (nxn), where in the first row ther'is the name of stocks, and in the other row the historical price. Then, I have another matrix of pair of stocks, for example:

Name_1  Name_2
Name_3 Name_5
and so on....

I want a code that give me for all pair the respective stock prince. For example for the first pair: Name_1 Name_2 I want to extrapolate the following matrix:

Name_1 Name_2
23.5   25.8
24.5   85.2
and so on.
