我试图将代码从Matlab转换为python。您能帮我将这段代码从Matlab转换为python吗？

在matlab代码中

z是列表，z长度是121

z = 7.0502 5.8030 4.4657 3.0404 1.5416 0 -1.5416 -3.0404 -4.4657 -5.8030 -7.0502 7.5944 6.3059 4.8990 3.3662 1.7189 0 -1.7189 -3.3662 -4.8990 -6.3059 -7.5944 8.2427 6.9282 5.4611 3.8122 1.9735 0 -1.9735 -3.8122 -5.4611 -6.9282 -8.2427 9.0135 7.7027 6.2075 4.4590 2.3803 0 -2.3803 -4.4590 -6.2075 -7.7027 -9.0135 9.9185 8.6576 7.2038 5.4466 3.1530 0 -3.1530 -5.4466 -7.2038 -8.6576 -9.9185 10.9545 9.7980 8.4853 6.9282 4.8990 0 -4.8990 -6.9282 -8.4853 -9.7980 -10.9545 12.0986 11.0885 9.9947 8.8128 7.6119 -6.9282 -7.6119 -8.8128 -9.9947 -11.0885 -12.0986 13.3133 12.4632 11.5988 10.7649 10.0829 -9.7980 -10.0829 -10.7649 -11.5988 -12。4632 -13.3133 14.5583 13.8564 13.1842 12.5910 12.1612 -12.0000 -12.1612 -12.5910 -13.1842 -13.8564 -14.5583 15.8011 15.2238 14.6969 14.2594 13.9626 -13.8564 -13.9626 -14.2594 -14.6969 -15.2238 -15.8011 17.0207 16.543-1 16.12.76.1684 -16.5431 -17.0207

Matlab代码：\[z，index\] = sort(abs(z));

代码后z = 0 0 0 0 0 0 1.5416 1.5416 1.7189 1.7189 1.9735 1.9735 2.3803 2.3803 3.0404 3.0404 3.1530 3.1530 3.3530 3.3662 3.3662 3.8122 3.8122 4.4590 4.4590 4.4657 4.4657 4.8990 4.8990 4.8990 4.8990 5.4466 5.4466 5.4611 5.4611 5.8030 5.8030 282075 6.9075 6.9075 7.0502 7.0502 7.2038 7.2038 7.5944 7.5944 7.6119 7.6119 7.7027 7.7027 8.2427 8.2427 8.4853 8.4853 8.6576 8.6576 8.8128 8.8128 9.0135 9.0135 9.7980 9.7980 9.7980 9.9185 9.9185 9.9185 9.9947 9.9947 10.0829 10.0829 17829 10.7649 10.988885 19540986 12.1612 12.1612 12.4632 12.4632 12.5910 12.5910 13.1842 13.1842 13.3133 13.3133 13.8564 13.8564 13.8564 13.9626 13.9626 14.2594 14.2594 14.5583 14.5583 14.6969 14.6969 14.6969 15.2238 15.2238 15.4919 15.5684 15.5684 15.7875 15.7875 15.8011 15.8011 16.12277.07.017

索引是

指数= 6 17 28 39 50 61 5 7 16 18 27 29 38 40 4 8 49 51 15 19 26 30 37 41 3 9 14 20 60 62 48 52 25 31 2 10 36 42 13 21 24 32 59 63 72 1 11 47 53 12 22 71 73 35 43 23 33 58 64 46 54 70 74 34 44 57 65 83 45 55 69 75 82 84 81 85 56 66 68 76 80 86 94 67 77 93 95 79 87 92 96 91 97 78 88 90 98 105 104 106 103 107 89 99 102 108 101 109 116 115 117 114 118 100 110 113 119 112 120 111121

那么python中的\[z，index\]是什么？

解决方案

您需要返回索引吗？如果不这样做，则可以使用：

z=abs(z)new\_list=sorted(map(abs,z))index=sorted(range(len(z)),key=lambdak:z\[k\])

其中x是输出，z是列表。
