NAME

SYNOPSIS

9       #include "hpl.h"
10
11       void  HPL_dlacpy( const int M, const int N, const double * A, const int
12       LDA, double * B, const int LDB );
13

DESCRIPTION

15       HPL_dlacpy copies an array A into an array B.
16

ARGUMENTS

18       M       (local input)           const int
19               On entry,  M specifies the number of rows of the arrays  A  and
20               B. M must be at least zero.
21
22       N       (local input)           const int
23               On  entry,   N specifies  the number of columns of the arrays A
24               and B. N must be at least zero.
25
26       A       (local input)           const double *
27               On entry, A points to an array of dimension (LDA,N).
28
29       LDA     (local input)           const int
30               On entry, LDA specifies the leading dimension of the  array  A.
31               LDA must be at least MAX(1,M).
32
33       B       (local output)          double *
34               On entry, B points to an array of dimension (LDB,N). On exit, B
35               is overwritten with A.
36
37       LDB     (local input)           const int
38               On entry, LDB specifies the leading dimension of the  array  B.
39               LDB must be at least MAX(1,M).

EXAMPLE

42       #include "hpl.h"
43
44       int main(int argc, char *argv[])
45       {
46          double a[2*2], b[2*2];
47          a[0] = 1.0; a[1] = 3.0; a[2] = 2.0; a[3] = 4.0;
48          HPL_dlacpy( 2, 2, a, 2, b, 2 );
49          printf("  [%f,%f]\n", b[0], b[2]);
50          printf("b=[%f,%f]\n", b[1], b[3]);
51          exit(0);
52          return(0);
53       }
