利用spcs2xt命令将截面矩阵的转换过程如下:
--------------------------
比如截面距离矩阵如下:
| 1 2 3 4
|-------------------------
| 0 1 1 1
| 1 0 1 0
| 1 1 0 1
| 1 0 1 0
|-------------------------
转换为空间距离矩阵如下:
(1) (2) (3) (4)
|-----------------|-----------------|-----------------|-----------------|
(1) | 0 0 0 0 | 1 0 0 0 | 1 0 0 0 | 1 0 0 0 |
| 0 0 0 0 | 0 1 0 0 | 0 1 0 0 | 0 1 0 0 |
| 0 0 0 0 | 0 0 1 0 | 0 0 1 0 | 0 0 1 0 |
| 0 0 0 0 | 0 0 0 1 | 0 0 0 1 | 0 0 0 1 |
|-----------------|-----------------|-----------------|-----------------|
(2) | 1 0 0 0 | 0 0 0 0 | 1 0 0 0 | 0 0 0 0 |
| 0 1 0 0 | 0 0 0 0 | 0 1 0 0 | 0 0 0 0 |
| 0 0 1 0 | 0 0 0 0 | 0 0 1 0 | 0 0 0 0 |
| 0 0 0 1 | 0 0 0 0 | 0 0 0 1 | 0 0 0 0 |
|-----------------|-----------------|-----------------|-----------------|
(3) | 1 0 0 0 | 1 0 0 0 | 0 0 0 0 | 1 0 0 0 |
| 0 1 0 0 | 0 1 0 0 | 0 0 0 0 | 0 1 0 0 |
| 0 0 1 0 | 0 0 1 0 | 0 0 0 0 | 0 0 1 0 |
| 0 0 0 1 | 0 0 0 1 | 0 0 0 0 | 0 0 0 1 |
|-----------------|-----------------|-----------------|-----------------|
(4) | 1 0 0 0 | 0 0 0 0 | 1 0 0 0 | 0 0 0 0 |
| 0 1 0 0 | 0 0 0 0 | 0 1 0 0 | 0 0 0 0 |
| 0 0 1 0 | 0 0 0 0 | 0 0 1 0 | 0 0 0 0 |
| 0 0 0 1 | 0 0 0 0 | 0 0 0 1 | 0 0 0 0 |

我的困惑在于:创造面板距离矩阵时,不是应该对角线上为相同的距离矩阵 其他为0矩阵吗?如下结构:
(1) (2) (3) (4)
|-----------------|-----------------|-----------------|-----------------|
(1)| 0 1 1 1 | 0 0 0 0 | 0 0 0 0 | 0 0 0 0 |
| 1 0 1 0 | 0 0 0 0 | 0 0 0 0 | 0 0 0 0 |
| 1 1 0 1 | 0 0 0 0 | 0 0 0 0 | 0 0 0 0 |
| 1 0 1 0 | 0 0 0 0 | 0 0 0 0 | 0 0 0 0 |
|-----------------|-----------------|-----------------|-----------------|
(2)| 0 0 0 0 | 0 1 1 1 | 0 0 0 0 | 0 0 0 0 |
| 0 0 0 0 | 1 0 1 0 | 0 0 0 0 | 0 0 0 0 |
| 0 0 0 0 | 1 1 0 1 | 0 0 0 0 | 0 0 0 0 |
| 0 0 0 0 | 1 0 1 0 | 0 0 0 0 | 0 0 0 0 |
-----------------|-----------------|-----------------|-----------------|
(3)| 0 0 0 0 | 0 0 0 0 | 0 1 1 1 | 0 0 0 0 |
| 0 0 0 0 | 0 0 0 0 | 1 0 1 0 | 0 0 0 0 |
| 0 0 0 0 | 0 0 0 0 | 1 1 0 1 | 0 0 0 0 |
| 0 0 0 0 | 0 0 0 0 | 1 0 1 0 | 0 0 0 0 |
|-----------------|-----------------|-----------------|-----------------|
(4)| 0 0 0 0 | 0 0 0 0 | 0 0 0 0 | 0 1 1 1 |
| 0 0 0 0 | 0 0 0 0 | 0 0 0 0 | 1 0 1 0 |
| 0 0 0 0 | 0 0 0 0 | 0 0 0 0 | 1 1 0 1 |
| 0 0 0 0 | 0 0 0 0 | 0 0 0 0 | 1 0 1 0 |

即我的理解应该是对角线上是每年的空间距离矩阵,不随时间变化的,其他为零矩阵。这样的理解是错的吗?还望大牛们指导!非常感谢~
