subroutine sqrt04 (m, n, nb, result)
SQRT04

SQRT04

Purpose:

 SQRT04 tests SGEQRT and SGEMQRT.

Parameters

M

          M is INTEGER
          Number of rows in test matrix.

N

          N is INTEGER
          Number of columns in test matrix.

NB

          NB is INTEGER
          Block size of test matrix.  NB <= Min(M,N).

RESULT

          RESULT is REAL array, dimension (6)
          Results of each of the six tests below.

          RESULT(1) = | A - Q R |
          RESULT(2) = | I - Q^H Q |
          RESULT(3) = | Q C - Q C |
          RESULT(4) = | Q^H C - Q^H C |
          RESULT(5) = | C Q - C Q |
          RESULT(6) = | C Q^H - C Q^H |
