 initial Replying to [comment:12 zimmerma]: > Nicolas Thiery just tested the doctests of our book with Sage 8.1beta5 and several do fail (while all tests pass with Sage 8.0). Here are the issues: > > 1) the {{{lil_matrix}}} do not work any more. Cf the example on page 299 of the english translation: > {{{ >   sage: from scipy.sparse.linalg.dsolve import * >   sage: from scipy.sparse import lil_matrix >   sage: from numpy import array >   sage: n = 200 >   sage: n2 = n*n >   sage: A = lil_matrix((n2, n2)) >   sage: h2 = 1./float((n+1)^2) >   sage: for i in range(0,n2): >   ....:    A[i,i]=4*h2+1. >   ....:    if i+1   ....:    if i>0:    A[i,int(i-1)]=-h2 >   ....:    if i+n   ....:    if i-n>=0: A[i,int(i-n)]=-h2 >   sage: Acsc = A.tocsc() >   sage: b = array([1 for i in range(0,n2)]) >   sage: solve = factorized(Acsc) # LU factorisation >   sage: S = solve(b)             # resolution > }}} > Now if fails at the {{{A = lil_matrix((n2, n2))}}} line with: > {{{ >     TypeError: unrecognized lil_matrix constructor usage > }}} > Aren't {{{lil_matrix}}} tested in the current doctests?
