Oops, I forgot to mention that I'm on: In []: sys.version Out[]: '2.7.2 (default, Jun 12 2011, 15:08:59) [MSC v.1500 32 bit (Intel)]' In []: np.version.version Out[]: '1.6.0' In []: sp.version.version Out[]: '0.9.0' On Wed, Aug 29, 2012 at 10:29 PM, eat <e.antero.tammi@gmail.com> wrote:
Hi,
Apparently I'm somehow misusing the functionality of interp1d(.) or does following behavior imply a bug in scipy. A minimum snippet (with plots) to demonstrate the problem: In []: from scipy.interpolate import interp1d In []: n= 1000 In []: x, y= randn(n), linspace(0, 1, n) In []: x.sort() In []: plot(x, y, lw= 2) Out[]: [<matplotlib.lines.Line2D object at 0x12E190D0>]
In []: f= interp1d(x, y, 'cubic') In []: xi= linspace(x.min(), x.max(), n) In []: plot(xi, f(xi)) Out[]: [<matplotlib.lines.Line2D object at 0x12E20830>]
