好的,这是一个技术问题,并且我可以回答。以下是一个示例代码,用于生成一个元胞自动机多维矩阵的多维邻居矩阵函数:
```
import numpy as np
def get_neighbors(matrix, cell_coords, neighborhood_size=1):
ndim = matrix.ndim
# 初始化邻居坐标矩阵
neighbor_coords = np.zeros((2 * neighborhood_size + 1) * ndim, dtype=np.int)
# 初始化邻居坐标索引
neighbor_offsets = np.arange(-neighborhood_size, neighborhood_size + 1)
neighbor_coords[(ndim - 1):] = cell_coords
for i in range(ndim):
neighbor_coords[i:(i + ndim - 1):ndim] = cell_coords[i] + neighbor_offsets
valid = np.ones_like(neighbor_coords[:ndim], dtype=bool)
for i in range(ndim):
valid = valid & (neighbor_coords[i:(i + ndim - 1):ndim] >= 0)
valid = valid & (neighbor_coords[i:(i + ndim - 1):ndim] < matrix.shape[i])
neighbor_coords = neighbor_coords.reshape((2 * neighborhood_size + 1,) * ndim, order='F')
neighbor_coords = neighbor_coords[valid]
# 返回值为邻居坐标矩阵
return neighbor_coords
```
该函数以一个多维矩阵,一个给定的细胞坐标和一个邻居大小作为输入,返回一个矩阵,其中包含了指定大小的邻居的坐标。
