Input File for Testing the Banded Symmetric Eigenvalue Routines and Drivers

An annotated example of an input file for testing the symmetric eigenvalue routines and drivers is shown below.

SSB:  Data file for testing Symmetric Eigenvalue Problem routines
2                                 Number of values of N
5 20                              Values of N (dimension)
5                                 Number of values of K
0 1 2 5 16                        Values of K (band width)
20.0                              Threshold value
T                                 Put T to test the error exits
1                                 Code to interpret the seed
SSB 15

The first line of the input file must contain the characters SEP in columns 1-3. Lines 2-12 are read using list-directed input and specify the following values:

line 2: The number of values of N
line 3: The values of N, the matrix dimension
line 4: The number of values of K
line 5: The values of K
line 6: The threshold value for the test ratios
line 7: TSTERR, flag to test error exits from LAPACK and driver routines
line 8: An integer code to interpret the random number seed
  = 0: Set the seed to a default value before each run
  = 1: Initialize the seed to a default value only before the first run
  = 2: Like 1, but use the seed values on the next line
line 9: If line 12 was 2, four integer values for the random number seed
   

The remaining lines are used to specify the matrix types for one or more sets of tests. The valid 3-character code is SSB (CSB in complex, DSB in double precision, and ZSB in complex*16).
