PROGRAM ZCHKAB
IMPLICIT NONE * * -- LAPACK test routine (version 3.2.1) -- * * -- April 2009 -- * * -- LAPACK is a software package provided by Univ. of Tennessee, -- * -- Univ. of California Berkeley, Univ. of Colorado Denver and NAG Ltd..-- * * Purpose * ======= * * ZCHKAB is the test program for the COMPLEX*16 LAPACK * ZCGESV/ZCPOSV 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 9 lines: * Data file for testing COMPLEX*16 LAPACK ZCGESV * 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 routine * 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 * The maximum allowable value for N * * 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 * * NOUT INTEGER * The unit number for output * * ===================================================================== * * ..
