For the LAPACK test paths shown in Table 1, each test matrix is subjected to the following tests:

- Factor the matrix using xxxTRF, and compute the ratio
- 27#27

- Invert the matrix 16#16 using xxxTRI, and compute the ratio
- 33#33

- Solve the system 34#34 using xxxTRS, and compute the ratios
- 35#35
- 36#36

- Use iterative refinement (xxxRFS) to improve the solution,
and compute the ratios
- 36#36
- (backward error) 38#38
- 39#39 (error bound) 40#40

- Compute the reciprocal condition number RCOND using xxxCON,
and compare to the value RCONDC which was computed as 1/(ANORM * AINVNM)
where AINVNM is the explicitly computed norm of 41#41.
The larger of the ratios
- 42#42 and 43#43
