Python | Numpy np.legmul() method

np.legmul() method is used to multiply one Legendre series to another.It returns the product of two Legendre series c1 * c2.
Syntax :
np.legmul(c1, c2)
Parameters:
c1, c2 :[ array_like ] 1-D arrays of Legendre series coefficients ordered from low to high.Return : [ndarray] Legendre series coefficients representing their product.
Code #1 :
