Description
HPL_dmatgen
generates (or regenerates) a random matrix A.
 
The  pseudo-random  generator uses the linear congruential algorithm:
X(n+1) = (a * X(n) + c) mod m  as  described  in the  Art of Computer
Programming, Knuth 1973, Vol. 2.
Arguments
M       (input)                       const int
        On entry,  M  specifies  the number  of rows of the matrix A.
        M must be at least zero.
N       (input)                       const int
        On entry,  N specifies the number of columns of the matrix A.
        N must be at least zero.
A       (output)                      double *
        On entry, A points to an array of dimension (LDA,N). On exit,
        this  array  contains   the   coefficients  of  the  randomly
        generated matrix.
LDA     (input)                       const int
        On entry, LDA specifies the leading dimension of the array A.
        LDA must be at least max(1,M).
ISEED   (input)                       const int
        On entry, ISEED  specifies  the  seed  number to generate the
        matrix A. ISEED must be at least zero.
