numpy.ma.asanyarray(a, dtype=None)
[source]
Convert the input to a masked array, conserving subclasses.
If a
is a subclass of MaskedArray
, its class is conserved. No copy is performed if the input is already an ndarray
.
Parameters: |
a : array_like Input data, in any form that can be converted to an array. dtype : dtype, optional By default, the data-type is inferred from the input data. order : {‘C’, ‘F’}, optional Whether to use row-major (‘C’) or column-major (‘FORTRAN’) memory representation. Default is ‘C’. |

Returns: |
