       Univ. of Tennessee, Univ. of California Berkeley, NAG Ltd.,   
       Courant Institute, Argonne National Lab, and Rice University   
       October 31, 1999   


    Purpose   
    =======   

    DDRVBD checks the singular value decomposition (SVD) drivers   
    DGESVD and SGESDD.   
    Both DGESVD and SGESDD factor A = U diag(S) VT, where U and VT are   
    orthogonal and diag(S) is diagonal with the entries of the array S   
    on its diagonal. The entries of S are the singular values,   
    nonnegative and stored in decreasing order.  U and VT can be   
    optionally not computed, overwritten on A, or computed partially.   

    A is M by N. Let MNMIN = min( M, N ). S has dimension MNMIN.   
    U can be M by M or M by MNMIN. VT can be N by N or MNMIN by N.   

    When DDRVBD is called, a number of matrix "sizes" (M's and N's)   
    and a number of matrix "types" are specified.  For each size (M,N)   
    and each type of matrix, and for the minimal workspace as well as   
    workspace adequate to permit blocking, an  M x N  matrix "A" will be   
    generated and used to test the SVD routines.  For each matrix, A will   
    be factored as A = U diag(S) VT and the following 12 tests computed:   

    Test for DGESVD:   

    (1)    | A - U diag(S) VT | / ( |A| max(M,N) ulp )   

    (2)    | I - U'U | / ( M ulp )   

    (3)    | I - VT VT' | / ( N ulp )   

    (4)    S contains MNMIN nonnegative values in decreasing order.   
           (Return 0 if true, 1/ULP if false.)   

    (5)    | U - Upartial | / ( M ulp ) where Upartial is a partially   
           computed U.   

    (6)    | VT - VTpartial | / ( N ulp ) where VTpartial is a partially   
           computed VT.   

    (7)    | S - Spartial | / ( MNMIN ulp |S| ) where Spartial is the   
           vector of singular values from the partial SVD   

    Test for DGESDD:   

    (8)    | A - U diag(S) VT | / ( |A| max(M,N) ulp )   

    (9)    | I - U'U | / ( M ulp )   

    (10)   | I - VT VT' | / ( N ulp )   

    (11)   S contains MNMIN nonnegative values in decreasing order.   
           (Return 0 if true, 1/ULP if false.)   

    (12)   | U - Upartial | / ( M ulp ) where Upartial is a partially   
           computed U.   

    (13)   | VT - VTpartial | / ( N ulp ) where VTpartial is a partially   
           computed VT.   

    (14)   | S - Spartial | / ( MNMIN ulp |S| ) where Spartial is the   
           vector of singular values from the partial SVD   

    The "sizes" are specified by the arrays MM(1:NSIZES) and   
    NN(1:NSIZES); the value of each element pair (MM(j),NN(j))   
    specifies one size.  The "types" are specified by a logical array   
    DOTYPE( 1:NTYPES ); if DOTYPE(j) is .TRUE., then matrix type "j"   
    will be generated.   
    Currently, the list of possible types is:   

    (1)  The zero matrix.   
    (2)  The identity matrix.   
    (3)  A matrix of the form  U D V, where U and V are orthogonal and   
         D has evenly spaced entries 1, ..., ULP with random signs   
         on the diagonal.   
    (4)  Same as (3), but multiplied by the underflow-threshold / ULP.   
    (5)  Same as (3), but multiplied by the overflow-threshold * ULP.   

    Arguments   
    ==========   

    NSIZES  (input) INTEGER   
            The number of matrix sizes (M,N) contained in the vectors   
            MM and NN.   

    MM      (input) INTEGER array, dimension (NSIZES)   
            The values of the matrix row dimension M.   

    NN      (input) INTEGER array, dimension (NSIZES)   
            The values of the matrix column dimension N.   

    NTYPES  (input) INTEGER   
            The number of elements in DOTYPE.   If it is zero, DDRVBD   
            does nothing.  It must be at least zero.  If it is MAXTYP+1   
            and NSIZES is 1, then an additional type, MAXTYP+1 is   
            defined, which is to use whatever matrices are in A and B.   
            This is only useful if DOTYPE(1:MAXTYP) is .FALSE. and   
            DOTYPE(MAXTYP+1) is .TRUE. .   

    DOTYPE  (input) LOGICAL array, dimension (NTYPES)   
            If DOTYPE(j) is .TRUE., then for each size (m,n), a matrix   
            of type j will be generated.  If NTYPES is smaller than the   
            maximum number of types defined (PARAMETER MAXTYP), then   
            types NTYPES+1 through MAXTYP will not be generated.  If   
            NTYPES is larger than MAXTYP, DOTYPE(MAXTYP+1) through   
            DOTYPE(NTYPES) will be ignored.   

    ISEED   (input/output) INTEGER array, dimension (4)   
            On entry, the seed of the random number generator.  The array   
            elements should be between 0 and 4095; if not they will be   
            reduced mod 4096.  Also, ISEED(4) must be odd.   
            On exit, ISEED is changed and can be used in the next call to   
            DDRVBD to continue the same random number sequence.   

    THRESH  (input) DOUBLE PRECISION   
            The threshold value for the test ratios.  A result is   
            included in the output file if RESULT >= THRESH.  The test   
            ratios are scaled to be O(1), so THRESH should be a small   
            multiple of 1, e.g., 10 or 100.  To have every test ratio   
            printed, use THRESH = 0.   

    A       (workspace) DOUBLE PRECISION array, dimension (LDA,NMAX)   
            where NMAX is the maximum value of N in NN.   

    LDA     (input) INTEGER   
            The leading dimension of the array A.  LDA >= max(1,MMAX),   
            where MMAX is the maximum value of M in MM.   

    U       (workspace) DOUBLE PRECISION array, dimension (LDU,MMAX)   

    LDU     (input) INTEGER   
            The leading dimension of the array U.  LDU >= max(1,MMAX).   

    VT      (workspace) DOUBLE PRECISION array, dimension (LDVT,NMAX)   

    LDVT    (input) INTEGER   
            The leading dimension of the array VT.  LDVT >= max(1,NMAX).   

    ASAV    (workspace) DOUBLE PRECISION array, dimension (LDA,NMAX)   

    USAV    (workspace) DOUBLE PRECISION array, dimension (LDU,MMAX)   

    VTSAV   (workspace) DOUBLE PRECISION array, dimension (LDVT,NMAX)   

    S       (workspace) DOUBLE PRECISION array, dimension   
                        (max(min(MM,NN)))   

    SSAV    (workspace) DOUBLE PRECISION array, dimension   
                        (max(min(MM,NN)))   

    E       (workspace) DOUBLE PRECISION array, dimension   
                        (max(min(MM,NN)))   

    WORK    (workspace) DOUBLE PRECISION array, dimension (LWORK)   

    LWORK   (input) INTEGER   
            The number of entries in WORK.  This must be at least   
            max(3*MN+MX,5*MN-4)+2*MN**2 for all pairs   
            pairs  (MN,MX)=( min(MM(j),NN(j), max(MM(j),NN(j)) )   

    IWORK   (workspace) INTEGER array, dimension at least 8*min(M,N)   

    NOUT    (input) INTEGER   
            The FORTRAN unit number for printing out error messages   
            (e.g., if a routine returns IINFO not equal to 0.)   

    INFO    (output) INTEGER   
            If 0, then everything ran OK.   
             -1: NSIZES < 0   
             -2: Some MM(j) < 0   
             -3: Some NN(j) < 0   
             -4: NTYPES < 0   
             -7: THRESH < 0   
            -10: LDA < 1 or LDA < MMAX, where MMAX is max( MM(j) ).   
            -12: LDU < 1 or LDU < MMAX.   
            -14: LDVT < 1 or LDVT < NMAX, where NMAX is max( NN(j) ).   
            -21: LWORK too small.   
            If  DLATMS, or DGESVD returns an error code, the   
                absolute value of it is returned.
