N lowest eigenvalues of the tridiagonal matrix in python

 ''' r = lamRange(d,c,N). Returns the sequence {r[0],r[1],...,r[N]} that separates the N lowest eigenvalues of the tridiagonal matrix [A] = [c\d\c]; that is, r[i] &lt; lam[i] &lt; r[i+1]. &#039;&#039;&#039; from numpy import ones from sturmSeq import * from gerschgorin import * def lamRange(d,c,N): lamMin,lamMax = gerschgorin(d,c) r = ones(N+1) r[0] = <div>Tangles be always damn.
