Fiedler Vector...............
I am performing spectral bisectioning on an unstructured mesh. I get the laplacian matrix and i have to compute the eigenvector corresponding to the 2nd smallest eigenvalue (this is called the Fiedler vector) of this matrix. Can anyone help me find an algorithm/source code which does this.
Note: 1. Matrix is symmetric and highly sparse 2. Only the 2nd smallest eigenpair is required 3. The smallest eigenvector is {1,1,1,1......1} corr. to the eigenvalue 0 |
