Hi all,

Who can resolve this problem ?

python2.3 -i failure.py

Traceback (most recent call last):
  File "failure.py", line 9, in ?
    x,info = linalg.gmres(A,r)
  File "/usr/lib/python2.3/site-packages/scipy/linalg/iterative.py", 
line 499, in gmres
    work[slice2] += sclr1*matvec(work[slice1])
TypeError: return array has incorrect type
