Do you mean >>A(3) and >>A(5) Note: unlike python here indexing starts with 1,2,....

In MATLAB, array indexing uses integers greater than zero, so indices corresponding to your vector elements 11 and 5 would be 4 and 6, respectively.

If all you want to know is the value of a certain part of the matrix just call the index.

A(3)
A(3) = 8

You can call multiple things with indexing, and you can add logic statements to check for certain values as well if you would like.
