• bl - Lower bandwidth of a.

• bu - Upper bandwidth of a.

• factors - Pointer to an internal structure that holds the factorization results.

• axis_r - Specifies the axis of array a whose extent is 1+2*bl+2*bu+1

• axis_d - Specifies the axis of array a whose extent is n.

• b - S3L array handle containing the right-hand side of the matrix equation ax=b.
