SLAFTS

Purpose:
    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.
  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.
