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。您能帮我将这段代码从Matlab转换为python吗？

使用Matlab代码

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 4.63.1-1 2.6-1 -1 -15.8 011 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 6.2 6.9 6.9059 6.3059 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 1212.5910 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 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 17.0207

并且索引是

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 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 80 94 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

所以python中的[z，index]是什么？

Answer 1

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=lambda k: z[k])

其中x是输出，z是列表。
