要点在哪里 (a, b, c) 由所有三个组成 a 从 x ， b 从 y 和 c 从 z . 结果点形成一个网格 x 在第一维度， y 在第二个，和 z 在第三。
参数 x ， y 和 z 只有当数组是元组或列表时才转换为数组，否则它们被视为标量。在任何一种情况下，要么 x ， y 和 z 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 少于三个维度，其中一个维度隐式附加到其形状上，使其成为三维的。结果的形状将是C形。 [3:] +x.shape+y.shape+z.shape。
三维级数是在笛卡尔积的点上进行计算的。 x ， y 和 z . 如果 x “Y”，或 z 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。
排列的系数数组，使i，j阶项的系数包含在 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]
笛卡尔积中点的二维多项式值 x 和 y .
