I need to do the inverse of a lower triangular matrix for which I need to choose elements (a_ij) = (i+j)^2 when i>j. choose the length n=8. I know the inverse of lower triangular matrix but don't know how to choose the elements so that the above conditions are satisfied. Help me please...

I=(1:8).';
J=I.';
A=tril( (I+J).^2 )
