[SciPy-user] Example 1 - Error

[Gael Varoquaux]

    I get another error in the example 1 :

In [20]: time xsp3 = linsolve.spsolve(Asp.tocsr(),b)
---------------------------------------------------------------------------
exceptions.AttributeError                            Traceback (most

    Maybe it is because my version of linsolve is not recent enough, but
it fails with enthon 1.0.0 beta4. That not to pretty to see when you are
doing the tutorial to see weather you are going to switch from Matlab to
scipy (as a colleague of mine was doing when he found the error).
