recarray.nonzero() Return the indices of the elements that are non-zero. Refer to

matrix.min(axis=None, out=None)

ndarray.dumps() Returns the pickle of the array as a string. pickle.loads or numpy.loads will convert the string back to

matrix.argsort(axis=-1, kind='quicksort', order=None) Returns the indices that would sort this array. Refer to

MaskedArray.__divmod__(y) <==> divmod(x, y)

MaskedArray.__and__ x.__and__(y) <==> x&y

recarray.round(decimals=0, out=None) Return a with each element rounded to the given number of decimals.

MaskedArray.take(indices, axis=None, out=None, mode='raise')

matrix.clip(min=None, max=None, out=None) Return an array whose values are limited to [min, max]. One of max or

ndarray.__int__() <==> int(x)
