在哪里？ 0 <= i <= l ， 0 <= j <= m 和 0 <= j <= n . 主要指标 V 索引点 (x, y, z) 最后一个索引编码了厄米特多项式的度数。

如果 V = hermevander3d(x, y, z, [xdeg, ydeg, zdeg]) ，然后是 V 对应于三维系数数组的元素 c 按顺序排列的形状（xdeg+1、ydeg+1、zdeg+1）

System Message: WARNING/2 (C_000，C_001，C_002，…，C_010，C_011，C_012，…)

和 np.dot(V, c.flat) 和 hermeval3d(x, y, z, c) 在环形交叉路口也一样。这种等效性对于最小二乘拟合和大量相同度数和采样点的三维厄米特级数的计算都是有用的。

参数

x，y，zarray_like: 点坐标数组，所有形状相同。根据元素是否复杂，数据类型将转换为float64或complex128。标量转换为一维数组。
deg英特列表: 窗体的最大度数列表 [x_deg, y_deg, z_deg] .

返回

vander3d恩达雷: 返回矩阵的形状为 x.shape + (order,) 在哪里 $order = (deg[0]+1)*(deg[1]+1)*(deg[2]+1)$ . 数据类型将与转换后的类型相同 x ， y 和 z .
