Input File for Testing the Generalized QR and RQ Factorization Routines

An annotated example of an input file for testing the generalized QR and RQ factorization routines is shown below.

GQR:  Data file for testing Generalized QR and RQ routines
3                   Number of values of M, P and N
0 3 10              Values of M 
0 5 20              Values of P 
0 3 30              Values of N
20.0                Threshold value of test ratio.
T                   Put T to test the error exits
1                   Code to interpret the seed
GQR 8               List matrix types on next line if 0 < NTYPES < 8

The first line of the input file must contain the characters GQR or GRQ in columns 1-3. Lines 2-9 are read using list-directed input and specify the following values:

line 2: The number of values of M, P and N
line 3: The values of M
line 4: The values of P
line 5: The values of N
line 6: The threshold value for the test ratios
line 7: TSTERR, flag to test the error exits
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 8 was 2, four integer values for the random number seed
  Otherwise, the path GQR or GRQ followed by the number of matrix types NTYPES
line 10: If 535#535, then specifies matrix types to be tested.
