在Python中,`ploy1d`是一个函数,属于NumPy库的一部分。它用于生成多项式对象,可以用于多项式的拟合、插值等操作。通过`np.poly1d`函数,你可以创建一次、二次或更高次的多项式对象。例如,`np.poly1d([a,b])`创建一个一次多项式,其中`a`和`b`是多项式的系数。同样,`np.poly1d([a,b,c])`创建一个二次多项式,`np.poly1d([a,b,c,d])`创建一个三次多项式,依此类推。这些多项式对象可以用于计算拟合值、插值值等操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span><span class="em">4</span>
