numpy.ma.MaskedArray.toflex() function Python (original) (raw)

Last Updated : 05 May, 2020

numpy.ma.MaskedArray.toflex() function transforms a masked array into a flexible-type array. The flexible type array that is returned will have two fields: the _data field and the _mask field. The _data field stores the _data part of the array and the _mask field stores the _mask part of the array.

Syntax : numpy.ma.MaskedArray.toflex(self)Return : [ndarray] A new flexible-type ndarray with two fields: the first element containing a value, the second element containing the corresponding mask boolean. The returned record shape matches self.shape.
