python - 从 Matlab 到 Python 代码 [z,index]=sort(abs(z));

Question

我正在尝试将代码从 matlab 转换为 python。您能帮我将此代码从 matlab 转换为 python 吗？

在 matlab 代码中

z 是列表，z 长度为 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 -4.89 90 -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 -14.25 94 -14.6969 -15.2238 -15.8011 17.0207 16.5431 16.1227 15.7875 15.5684 -15.4919 -15.5684 -15.7875 -16.1227 -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 3.3662 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 6.2075 6.2075 6.3059 6.3059 6.9282 6.9282 6.9282 6.9282 6.9282 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 9.9947 9.9947 10.0829 10.0829 10.7649 10.7649 10.9545 10.9545 11.0885 11.0885 11.5988 11.5 988 12.0000 12.0986 12.0986 12.1612 12.1612 12.4632 12.4632 12.591012.5910 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 1 4.6969 15.2238 15.2238 15.4919 15.5684 15.5684 15.7875 15.7875 15.8011 15.8011 16.1227 16.1227 16.5431 16.5431 17.0207 17.0 207

索引是

索引 = 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 3 2 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 99 102 108 101 109 116 115 117 114 118 100 110 113 119 112 120 111 121

那么Python中的[z,index]是什么？

Answer 1

需要返回索引吗？如果不这样做，您可以使用:

z = abs(z)    
new_list = sorted(map(abs, z))
index = sorted(range(len(z)), key=lambda k: z[k])

其中 x 是输出，z 是列表。
