Question

NumPy中的多项式可以使用NumPy 1.4中引入的numpy.polynomialopen in new window程序包的Using the Convenience Classesopen in new window创建，操纵甚至拟合。

在NumPy 1.4之前，numpy.poly1dopen in new window是选择的类，为了保持向后兼容性，仍可以使用。 但是，较新的Polynomial软件包比numpy.poly1dopen in new window更完整，并且其便利类在numpy环境中表现更好。 因此，建议多项式用于新编码。

过渡通知

多项式程序包中的各种例程均处理其系数从零度开始向上的级数，这与Poly1d约定的顺序相反。 记住这一点的简单方法是索引对应于度，即coef [i]是度i项的系数。
