示例1: main
int main(int argc, char* argv[])
{
#ifdef HAVE_MPI
MPI_Init(&argc,&argv);
#endif
// Creating an instance of the BLAS class for double-precision kernels looks like:
Teuchos::BLAS<int, double> blas;
// This instance provides the access to all the BLAS kernels listed in Figure \ref{blas_kernels}:
const int n = 10;
double alpha = 2.0;
double x[ n ];
for ( int i=0; i<n; i++ ) { x[i] = i; }
blas.SCAL( n, alpha, x, 1 );
int max_idx = blas.IAMAX( n, x, 1 );
cout<< "The index of the maximum magnitude entry of x[] is the "
<< max_idx <<"-th and x[ " << max_idx-1 << " ] = "<< x[max_idx-1]
<< endl;
#ifdef HAVE_MPI
MPI_Finalize();
#endif
return 0;
