lynomial (relative to the "standard" basis) ordered
from lowest to highest degree.

Parameters
----------
c : array_like
    1-D array containing the Legendre series coefficients, ordered
    from lowest order term to highest.

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
--------
poly2leg

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

Examples
--------
>>> from numpy import polynomial as P
>>> c = P.Legendre(range(4))
>>> c
Legendre([0., 1., 2., 3.], domain=[-1.,  1.], window=[-1.,  1.], symbol='x')
>>> p = c.convert(kind=P.Polynomial)
>>> p
Polynomial([-1. , -3.5,  3. ,  7.5], domain=[-1.,  1.], window=[-1., ...
>>> P.legendre.leg2poly(range(4))
array([-1. , -3.5,  3. ,  7.5])
