How can i extract in Simulink 6 elements from matrix 3x3 if all the elements are variables?

How can i extract (get) in Simulink 6 elements from matrix 3x3 if all the elements in the Matrix are variables? The Matrix is like:

a11 a12 a13

a21 a22 a23

a31 a32 a33

I need to extract (get) 6 elements:

a11 a12 a13

a22 a23

a33

I don't need a triangular matrix. I only need 6 elements in order to send them to Scope block.
