numpy.ma.masked_greater   ma.masked_greater(x, value, copy=True)[source]
 
Mask an array where greater than a given value. This function is a shortcut to masked_where, with condition = (x > value).  See also  masked_where

Mask where a condition is met.    Examples >>> import numpy.ma as ma
>>> a = np.arange(4)
>>> a
array([0, 1, 2, 3])
>>> ma.masked_greater(a, 2)
