PROGRAM DCHKAA
*
* -- LAPACK test routine (version 3.1.1) --
* Univ. of Tennessee, Univ. of California Berkeley and NAG Ltd..
* January 2007
*
* Purpose
* =======
*
* DCHKAA is the main test program for the DOUBLE PRECISION LAPACK
* linear equation routines
*
* The program must be driven by a short data file. The first 14 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 36 lines:
* Data file for testing DOUBLE PRECISION LAPACK linear eqn. routines
* 7 Number of values of M
* 0 1 2 3 5 10 16 Values of M (row dimension)
* 7 Number of values of N
* 0 1 2 3 5 10 16 Values of N (column dimension)
* 1 Number of values of NRHS
* 2 Values of NRHS (number of right hand sides)
* 5 Number of values of NB
* 1 3 3 3 20 Values of NB (the blocksize)
* 1 0 5 9 1 Values of NX (crossover point)
* 3 Number of values of RANK
* 30 50 90 Values of rank (as a % of N)
* 20.0 Threshold value of test ratio
* T Put T to test the LAPACK routines
* T Put T to test the driver routines
* T Put T to test the error exits
