/* -- LAPACK timing routine (version 3.0) --
Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,
Courant Institute, Argonne National Lab, and Rice University
June 30, 1999
Purpose
=======
STIMQP times the LAPACK routines to perform the QR factorization with
column pivoting of a REAL general matrix.
Two matrix types may be used for timing. The number of types is
set in the parameter NMODE and the matrix types are set in the vector
MODES, using the following key:
2. BREAK1 D(1:N-1)=1 and D(N)=1.0/COND in SLATMS
3. GEOM D(I)=COND**(-(I-1)/(N-1)) in SLATMS
These numbers are chosen to correspond with the matrix types in the
test code.
Arguments
=========
LINE (input) CHARACTER*80
The input line that requested this routine. The first six
characters contain either the name of a subroutine or a
generic path name. The remaining characters may be used to
specify the individual routines to be timed. See ATIMIN for
a full description of the format of the input line.
NM (input) INTEGER
The number of values of M and N contained in the vectors
MVAL and NVAL. The matrix sizes are used in pairs (M,N).
MVAL (input) INTEGER array, dimension (NM)
The values of the matrix row dimension M.
NVAL (input) INTEGER array, dimension (NM)
The values of the matrix column dimension N.
NLDA (input) INTEGER
The number of values of LDA contained in the vector LDAVAL.

The values of the leading dimension of the array A.
TIMMIN (input) REAL
The minimum time a subroutine will be timed.
A (workspace) REAL array, dimension (LDAMAX*NMAX)
where LDAMAX and NMAX are the maximum values of LDA and N.
COPYA (workspace) REAL array, dimension (LDAMAX*NMAX)
TAU (workspace) REAL array, dimension (min(M,N))
WORK (workspace) REAL array, dimension (3*NMAX)
IWORK (workspace) INTEGER array, dimension (2*NMAX)
RESLTS (workspace) REAL array, dimension
(LDR1,LDR2,NLDA)
The timing results for each subroutine over the relevant
values of MODE, (M,N), and LDA.
LDR1 (input) INTEGER
The first dimension of RESLTS. LDR1 >= max(1,NM).
LDR2 (input) INTEGER
The second dimension of RESLTS. LDR2 >= max(1,NM).
NOUT (input) INTEGER
The unit number for output.

Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,

March 31, 1993
Purpose
=======
ZTIMTD times the LAPACK routines ZHETRD, ZUNGTR, and CUNMTR.
Arguments
=========
LINE (input) CHARACTER*80
The input line that requested this routine. The first six
characters contain either the name of a subroutine or a
generic path name. The remaining characters may be used to
specify the individual routines to be timed. See ATIMIN for
a full description of the format of the input line.
NM (input) INTEGER
The number of values of M contained in the vector MVAL.
MVAL (input) INTEGER array, dimension (NM)
The values of the matrix size M.
NN (input) INTEGER
The number of values of N contained in the vector NVAL.
NVAL (input) INTEGER array, dimension (NN)
The values of the matrix column dimension N.
NNB (input) INTEGER
The number of values of NB and NX contained in the
vectors NBVAL and NXVAL. The blocking parameters are used
in pairs (NB,NX).
NBVAL (input) INTEGER array, dimension (NNB)
The values of the blocksize NB.
NXVAL (input) INTEGER array, dimension (NNB)
The values of the crossover point NX.
NLDA (input) INTEGER
The number of values of LDA contained in the vector LDAVAL.
LDAVAL (input) INTEGER array, dimension (NLDA)
The values of the leading dimension of the array A.
TIMMIN (input) DOUBLE PRECISION
The minimum time a subroutine will be timed.
A (workspace) COMPLEX*16 array, dimension (LDAMAX*NMAX)
where LDAMAX and NMAX are the maximum values of LDA and N.
B (workspace) COMPLEX*16 array, dimension (LDAMAX*NMAX)
D (workspace) DOUBLE PRECISION array, dimension (2*NMAX-1)
TAU (workspace) COMPLEX*16 array, dimension (NMAX)
WORK (workspace) COMPLEX*16 array, dimension (NMAX*NBMAX)
where NBMAX is the maximum value of NB.
RESLTS (workspace) DOUBLE PRECISION array, dimension
(LDR1,LDR2,LDR3,4*NN+3)
The timing results for each subroutine over the relevant
values of M, (NB,NX), LDA, and N.
LDR1 (input) INTEGER
The first dimension of RESLTS. LDR1 >= max(1,NNB).
LDR2 (input) INTEGER
The second dimension of RESLTS. LDR2 >= max(1,NM).
LDR3 (input) INTEGER
The third dimension of RESLTS. LDR3 >= max(1,2*NLDA).
NOUT (input) INTEGER
The unit number for output.
Internal Parameters
===================
MODE INTEGER
The matrix type. MODE = 3 is a geometric distribution of
eigenvalues. See ZLATMS for further details.
COND DOUBLE PRECISION
The condition number of the matrix. The singular values are
set to values from DMAX to DMAX/COND.
DMAX DOUBLE PRECISION
The magnitude of the largest singular value.
