*> \brief \b SLAFTS
*
* =========== DOCUMENTATION ===========
*
* Online html documentation available at
* http://www.netlib.org/lapack/explore-html/
*
* Definition:
* ===========
*
* SUBROUTINE SLAFTS( TYPE, M, N, IMAT, NTESTS, RESULT, ISEED,
* THRESH, IOUNIT, IE )
*
* .. Scalar Arguments ..
* CHARACTER*3 TYPE
* INTEGER IE, IMAT, IOUNIT, M, N, NTESTS
* REAL THRESH
* ..
* .. Array Arguments ..
* INTEGER ISEED( 4 )
* REAL RESULT( * )
* ..
*
*
*> \par Purpose:
* =============
*>
*> \verbatim
*>
*> SLAFTS tests the result vector against the threshold value to
*> see which tests for this matrix type failed to pass the threshold.
*> Output is to the file given by unit IOUNIT.
*> \endverbatim
*
* Arguments:
* ==========
*
*> \verbatim
*> TYPE - CHARACTER*3
*> On entry, TYPE specifies the matrix type to be used in the
*> printed messages.
*> Not modified.
*>
*> N - INTEGER
*> On entry, N specifies the order of the test matrix.
*> Not modified.
*>
*> IMAT - INTEGER
*> On entry, IMAT specifies the type of the test matrix.
*> A listing of the different types is printed by SLAHD2
*> to the output file if a test fails to pass the threshold.
*> Not modified.
*>
*> NTESTS - INTEGER
*> On entry, NTESTS is the number of tests performed on the
*> subroutines in the path given by TYPE.
*> Not modified.
*>
*> RESULT - REAL array of dimension( NTESTS )
*> On entry, RESULT contains the test ratios from the tests
*> performed in the calling program.
*> Not modified.
*>
*> ISEED - INTEGER array of dimension( 4 )
*> Contains the random seed that generated the matrix used
*> for the tests whose ratios are in RESULT.
*> Not modified.
*>
*> THRESH - REAL
*> On entry, THRESH specifies the acceptable threshold of the
*> test ratios. If RESULT( K ) > THRESH, then the K-th test
*> did not pass the threshold and a message will be printed.
*> Not modified.
*>
*> IOUNIT - INTEGER
*> On entry, IOUNIT specifies the unit number of the file
*> to which the messages are printed.
*> Not modified.
*>
*> IE - INTEGER
*> On entry, IE contains the number of tests which have
*> failed to pass the threshold so far.
*> Updated on exit if any of the ratios in RESULT also fail.
