### Problem with SEP

**Sun May 28, 2006 9:52 pm**Hello.

I have some questions on LAPACK TESTING.Some reslut of SEP is abnormal.The output file is as follow:

Tests of the Hermitian Eigenvalue Problem routines

LAPACK VERSION 3.0, released June 30, 1999

The following parameter values will be used:

M: 0 512 513

N: 0 512 513

NB: 1 2 3 4 5

NBMIN: 2 2 2 2 2

NX: 1 0 5 9 1

Relative machine underflow is taken to be 0.117549E-37

Relative machine overflow is taken to be 0.340282E+39

Relative machine precision is taken to be 0.596046E-07

Routines pass computational tests if test ratio is less than 500.00

CST routines passed the tests of the error exits (114 tests done)

SEP: NB = 1, NBMIN = 2, NX = 1

CST -- Complex Hermitian eigenvalue problem

Matrix types (see CCHKST for details):

Special Matrices:

1=Zero matrix. 5=Diagonal: clustered entries.

2=Identity matrix. 6=Diagonal: large, evenly spaced.

3=Diagonal: evenly spaced entries. 7=Diagonal: small, evenly spaced.

4=Diagonal: geometr. spaced entries.

Dense Hermitian Matrices:

8=Evenly spaced eigenvals. 12=Small, evenly spaced eigenvals.

9=Geometrically spaced eigenvals. 13=Matrix with random O(1) entries.

10=Clustered eigenvalues. 14=Matrix with large random entries.

11=Large, evenly spaced eigenvals. 15=Matrix with small random entries.

16=Positive definite, evenly spaced eigenvalues

17=Positive definite, geometrically spaced eigenvlaues

18=Positive definite, clustered eigenvalues

19=Positive definite, small evenly spaced eigenvalues

20=Positive definite, large evenly spaced eigenvalues

21=Diagonally dominant tridiagonal, geometrically spaced eigenvalues

Test performed: see CCHKST for details.

If someone has had a similar problem or know how to help me I would greatly appreciate it.
