*> \verbatim
|
|
*>
|
|
*> CDRVRFP tests the LAPACK RFP routines:
|
|
*> CPFTRF, CPFTRS, and CPFTRI.
|
|
*>
|
|
*> This testing routine follow the same tests as CDRVPO (test for the full
|
|
*> format Symmetric Positive Definite solver).
|
|
*>
|
|
*> The tests are performed in Full Format, convertion back and forth from
|
|
*> full format to RFP format are performed using the routines CTRTTF and
|
|
*> CTFTTR.
|
|
*>
|
|
*> First, a specific matrix A of size N is created. There is nine types of
|
|
*> different matrixes possible.
|
|
*> 1. Diagonal 6. Random, CNDNUM = sqrt(0.1/EPS)
|
|
*> 2. Random, CNDNUM = 2 7. Random, CNDNUM = 0.1/EPS
|
|
*> *3. First row and column zero 8. Scaled near underflow
|
|
*> *4. Last row and column zero 9. Scaled near overflow
|
|
*> *5. Middle row and column zero
|
|
*> (* - tests error exits from CPFTRF, no test ratios are computed)
|
|
*> A solution XACT of size N-by-NRHS is created and the associated right
|
|
*> hand side B as well. Then CPFTRF is called to compute L (or U), the
|
|
*> Cholesky factor of A. Then L (or U) is used to solve the linear system
|
|
*> of equations AX = B. This gives X. Then L (or U) is used to compute the
|
|
*> inverse of A, AINV. The following four tests are then performed:
|
|
*> (1) norm( L*L' - A ) / ( N * norm(A) * EPS ) or
|
|
*> norm( U'*U - A ) / ( N * norm(A) * EPS ),
|
|
*> (2) norm(B - A*X) / ( norm(A) * norm(X) * EPS ),
|
|
*> (3) norm( I - A*AINV ) / ( N * norm(A) * norm(AINV) * EPS ),
|
|
*> (4) ( norm(X-XACT) * RCOND ) / ( norm(XACT) * EPS ),
|
|
*> where EPS is the machine precision, RCOND the condition number of A, and
|
|
*> norm( . ) the 1-norm for (1,2,3) and the inf-norm for (4).
|
|
*> Errors occur when INFO parameter is not as expected. Failures occur when
|
|
*> a test ratios is greater than THRES.
