[Help-gsl] Help - Principal Eigen Vector Calculation |

Hello,
Can you suggest me any implementation (in c/c++) of Principal eigen
vector calculation of an input matrix(e.g. Power method)?
One of the standard methods of Principal eigen vector calculation is
Power method.
I require reliable implementation (c/c++) (bug free) or any library
implemented in (c/c++).
Although principal eigen vector can be calculated from function provided
by gsl library. But this method also involves eigen value calculation.
While I am looking for method that only calculates principal eigen
vector.
Regards:
Ashish
