[54,18,44,79,0,51,34,56,48,93,80,72,90,84],

[140,111,137,70,93,42,126,90,61,0,114,90,72,25],
[26,98,124,108,80,80,62,57,53,114,0,24,95,89],
[50,90,116,84,72,56,38,33,29,90,24,0,71,65],
[121,108,134,97,90,69,107,71,42,72,95,71,0,47],
[115,102,128,91,84,93,101,65,36,25,89,65,47,0]
])
未定义变量 "np" 或类 "np.array"。
matlab这样报错怎么弄呀
