Python program to evaluate a pol

下面代码内容是关于Python program to evaluate a polynomial with its derivatives的代码。

## module evalPoly

''' p,dp,ddp = evalPoly(a,x).

    Evaluates the polynomial

    with its derivatives dp = p' and ddp = p"

    at x.

'''

def evalPoly(a,x): 

    n = len(a) - 1

    p = a[n]

    dp = 0.0 + 0.0j

    ddp = 0.0 + 0.0j

    for i in range(1,n+1):

    return p,dp,ddp
