numpy.polynomial.laguerre.Laguerre.degree

method

polynomial.laguerre.Laguerre.degree()

The degree of the series.

Returns:

degreeint

Degree of the series, one less than the number of coefficients.

Examples

Create a polynomial object for 1 + 7*x + 4*x**2:

>>> np.polynomial.set_default_printstyle("unicode")
>>> poly = np.polynomial.Polynomial([1, 7, 4])
>>> print(poly)
1.0 + 7.0·x + 4.0·x²
>>> poly.degree()
2

Note that this method does not check for non-zero coefficients. You must trim the polynomial to remove any trailing zeroes:

>>> poly = np.polynomial.Polynomial([1, 7, 0])
>>> print(poly)
1.0 + 7.0·x + 0.0·x²
>>> poly.degree()
2
>>> poly.trim().degree()
1
