Re: bug in vector summation???

 

No wonder, the sum() function in uBlasVector has the following elegant
implementation:

real uBlasVector::sum() const
{
  return sum();
}

:-)

Replace with the following (will commit this update shortly):

real uBlasVector::sum() const
{
  // FIXME: Find suitable uBlas call to compute sum
  real s = 0.0;
  for (uint i = 0; i < size(); i++)
    s += (this)[i];
  return s;
}
