print $d->format("Y-m-d H:i:s.u"); // note at point on "u"

How do I compute derivative using Numpy?
...y I can think of is using numpy's gradient function:
x = numpy.linspace(0,10,1000)
dx = x[1]-x[0]
y = x**2 + 1
dydx = numpy.gradient(y, dx)
This way, dydx will be computed using central differences and will have the same length as y, unlike numpy.diff, which uses forward differences and will retu...
