Warning: arange is dangerous

arange’s upper limit may or may not be included (due to round-off

errors)

Better to use a safer method: seq(start, stop, increment)

>>> from scitools.numpyutils import seq

>>> x = seq(-5, 5, 1)

>>> print x # upper limit always included

[-5. -4. -3. -2. -1. 0. 1. 2. 3. 4. 5.]

The package scitools is available at
