/*     Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd.. */
/*     January 2007 */

/*  Purpose */
/*  ======= */

/*  DCHKAB is the test program for the DOUBLE PRECISION LAPACK */
/*  DSGESV/DSPOSV routine */

/*  The program must be driven by a short data file. The first 5 records */
/*  specify problem dimensions and program options using list-directed */
/*  input. The remaining lines specify the LAPACK test paths and the */
/*  number of matrix types to use in testing.  An annotated example of a */
/*  data file can be obtained by deleting the first 3 characters from the */
/*  following 10 lines: */
/*  Data file for testing DOUBLE PRECISION LAPACK DSGESV */
/*  7                      Number of values of M */
/*  0 1 2 3 5 10 16        Values of M (row dimension) */
/*  1                      Number of values of NRHS */
/*  2                      Values of NRHS (number of right hand sides) */
/*  20.0                   Threshold value of test ratio */
/*  T                      Put T to test the LAPACK routines */
/*  T                      Put T to test the error exits */
/*  DGE    11              List types on next line if 0 < NTYPES < 11 */
/*  DPO    9               List types on next line if 0 < NTYPES <  9 */

/*  Internal Parameters */
/*  =================== */

/*  NMAX    INTEGER */

/*  MAXIN   INTEGER */
/*          The number of different values that can be used for each of */
/*          M, N, NRHS, NB, and NX */

/*  MAXRHS  INTEGER */
/*          The maximum number of right hand sides */

/*  NIN     INTEGER */
/*          The unit number for input */
