Interpretation of Choleski composition matrices

[alps]

Hello,
I ran a SVAR using the lower triangle restriction and got the impulse and varience composition numbers.

Then I viewed the calculated A and B matrices. Is there a way of interpreting these numbers in the matrices? Do they mean anything? Thanks.
