I am using [Evec,Eval]=eigs(H,1,’sa’) in Matlab to compute the smallest eigenvalue of a sparse matrix H. Can I get the error of the smallest eigenvalue as a function of iteration step?

The error? what error? – Ander Biguri Dec 01 '15 at 10:42

Error means the convergence of \Delta Eval as the iteration step increases? – Timothy Dec 01 '15 at 16:47

But, `Eval` are eigenvalues. Convergence to what? iteration of what? the algorithm inside `eigs`? – Ander Biguri Dec 01 '15 at 16:49

Yes, the algorithm inside eigs. – Timothy Dec 02 '15 at 02:19

You cant. The only option is writing the algorithm yourself. – Ander Biguri Dec 02 '15 at 09:24
