Resample Python Numpy

def resample(x, factor, kind='linear'):
    n = np.ceil(x.size / factor)
    f = interp1d(np.linspace(0, 1, x.size), x, kind)
    return f(np.linspace(0, 1, n))
 
e.g.:

a = np.array([1,2,3,4,5,6,7,8,9,10])
resample(a, factor=1.5, kind='linear')

yields

array([ 1. ,  2.5,  4. ,  5.5,  7. ,  8.5, 10. ])

and

a = np.array([1,2,3,4,5,6,7,8,9,10])
resample(a, factor=1.5, kind='nearest')

array([ 1.,  2.,  4.,  5.,  7.,  8., 10.])
