In a very large sparse matrix I want to use eigs function to find all non-negative eigenvalues and corresponding eigenvectors, is it possible?

Yes it is. At least if its a symmetric matrix. Else you can only get n-2 eigenvalues, where (n,n) is the size of the matrix. Just output all the eigenvalues and then get the non-negative ones.

So I guess you're asking if there is an option to set to get only non-negative eigenvalues, which there isn't. Why isn't doing it in more steps not good enough if I may ask?
