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

record.itemset() Not implemented (virtual attribute) Class generic exists solely to derive numpy scalars from, and

recarray.trace(offset=0, axis1=0, axis2=1, dtype=None, out=None) Return the sum along diagonals of the array. Refer

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

recarray.itemsize Length of one array element in bytes. Examples

matrix.getT()

recarray.flatten(order='C') Return a copy of the array collapsed into one dimension.

recarray.dtype Data-type of the array?s elements.
