numpy slicing (subtract prior from next element check that 'all' the 
results are >=0):

In [1]: import numpy

In [2]: x=numpy.array([1,2,3,4,5])

In [3]: (x[1:]-x[:-1])>=0
Out[3]: array([ True,  True,  True,  True], dtype=bool)

In [4]: numpy.all((x[1:]-x[:-1])>=0)
Out[4]: True

In [5]: x=numpy.array([1,3,2,5,4])

In [6]: numpy.all((x[1:]-x[:-1])>=0)
Out[6]: False
