Matlab uses BLAS and LAPACK.

http://www.physics.orst.edu/~rubin/nacphy/lapack/eigen.html

If you want to know the actual implementation, then you should ask the Mathworks. They might not be so forthcoming in exposing the guts of Matlab though...

Note that both BLAS and LAPACK can be linked in a C program, so you'd just be reinventing the wheel.
