numpy.polynomial.polynomial.Polynomial.cast#

method

classmethod polynomial.polynomial.Polynomial.cast(series, domain=None, window=None)[source]#

Convert series to series of this class.

The series is expected to be an instance of some polynomial series of one of the types supported by by the numpy.polynomial module, but could be some other class that supports the convert method.

Parameters:

seriesseries: The series instance to be converted.
domain{None, array_like}, optional: If given, the array must be of the form [beg, end], where beg and end are the endpoints of the domain. If None is given then the class domain is used. The default is None.
window{None, array_like}, optional: If given, the resulting array must be if the form [beg, end], where beg and end are the endpoints of the window. If None is given then the class window is used. The default is None.

Returns:

new_seriesseries: A series of the same kind as the calling class and equal to series when evaluated.
