Returns
-------
pol : ndarray
    1-D array containing the coefficients of the equivalent polynomial
    (relative to the "standard" basis) ordered from lowest order term
    to highest.

See Also
--------
poly2lag

Notes
-----
The easy way to do conversions between polynomial basis sets
is to use the convert method of a class instance.

Examples
--------
>>> from numpy.polynomial.laguerre import lag2poly
>>> lag2poly([ 23., -63.,  58., -18.])
array([0., 1., 2., 3.])
