25*> \par Purpose:
26* =============
27*>
28*> \verbatim
29*>
30*> DLAFTS tests the result vector against the threshold value to
31*> see which tests for this matrix type failed to pass the threshold.
32*> Output is to the file given by unit IOUNIT.
33*> \endverbatim
34*
35* Arguments:
36* ==========
37*
38*> \verbatim
39*> TYPE - CHARACTER*3
40*> On entry, TYPE specifies the matrix type to be used in the
41*> printed messages.
42*> Not modified.
43*>
44*> N - INTEGER
45*> On entry, N specifies the order of the test matrix.
46*> Not modified.
47*>
48*> IMAT - INTEGER
49*> On entry, IMAT specifies the type of the test matrix.
50*> A listing of the different types is printed by DLAHD2
51*> to the output file if a test fails to pass the threshold.
52*> Not modified.
53*>
54*> NTESTS - INTEGER
55*> On entry, NTESTS is the number of tests performed on the
56*> subroutines in the path given by TYPE.
57*> Not modified.
58*>
59*> RESULT - DOUBLE PRECISION array of dimension( NTESTS )
60*> On entry, RESULT contains the test ratios from the tests
61*> performed in the calling program.
62*> Not modified.
63*>
64*> ISEED - INTEGER array of dimension( 4 )
65*> Contains the random seed that generated the matrix used
66*> for the tests whose ratios are in RESULT.
67*> Not modified.
68*>
69*> THRESH - DOUBLE PRECISION
70*> On entry, THRESH specifies the acceptable threshold of the
71*> test ratios. If RESULT( K ) > THRESH, then the K-th test
72*> did not pass the threshold and a message will be printed.
73*> Not modified.
74*>
75*> IOUNIT - INTEGER
76*> On entry, IOUNIT specifies the unit number of the file
77*> to which the messages are printed.
78*> Not modified.
79*>
80*> IE - INTEGER
81*> On entry, IE contains the number of tests which have
82*> failed to pass the threshold so far.
83*> Updated on exit if any of the ratios in RESULT also fail.
