参数 x 和 y 仅当它们是元组或列表时才转换为数组，否则它们将被视为标量，并且在转换后它们必须具有相同的形状。在任何一种情况下，要么 x 和 y 或者它们的元素必须同时支持自身和元素的乘法和加法。 c .
如果 c 是一个一维数组，在其形状上隐式附加一个数组，使其成为二维数组。结果的形状将是c.shape。 [2:] +X.形状。
二维级数是在点上计算的。 (x, y) 在哪里 x 和 y 必须具有相同的形状。如果 x 或 y 是一个列表或元组，它首先被转换为一个ndarray，否则它将保持不变，如果它不是一个ndarray，它将被视为一个标量。
有序排列的系数数组，使多阶i，j项的系数包含在 c[i,j] .如果 c 维度大于两个，其余索引枚举多组系数。
c[i,j]
二维多项式在对应值对形成的点上的值 x 和 y .
