使用特定格式在Octave中加载文本数据 [英] Loading text data in Octave with specific format
问题描述
我有一个我想要存储的数据集，并且能够在Octave中加载
I have a data set that I would like to store and be able to load in Octave
18.0 8 307.0 130.0 3504. 12.0 70 1 "chevrolet chevelle malibu"
15.0 8 350.0 165.0 3693. 11.5 70 1 "buick skylark 320"
18.0 8 318.0 150.0 3436. 11.0 70 1 "plymouth satellite"
16.0 8 304.0 150.0 3433. 12.0 70 1 "amc rebel sst"
17.0 8 302.0 140.0 3449. 10.5 70 1 "ford torino"
15.0 8 429.0 198.0 4341. 10.0 70 1 "ford galaxie 500"
14.0 8 454.0 220.0 4354. 9.0 70 1 "chevrolet impala"
14.0 8 440.0 215.0 4312. 8.5 70 1 "plymouth fury iii"
14.0 8 455.0 225.0 4425. 10.0 70 1 "pontiac catalina"
15.0 8 390.0 190.0 3850. 8.5 70 1 "amc ambassador dpl"
它不起作用IM当我尝试使用时，中间地：
It does not work immediately when I try to use:
data = load('auto.txt')
有没有办法从给定格式的文本文件加载，或者我需要将其转换为例如
Is there a way to load from a text files with the given format or do I need to convert it to e.g
18.0,8,307.0,130.0,3504.0,12.0,70,1
...
编辑：
删除最后一行并修复一半数字，例如3504. - > 3504.0
然后使用：
Deleting the last row and fixing the 'half' number e.g. 3504. -> 3504.0 and then used:
data = load('-ascii','autocleaned.txt');
将所需数据加载到Octave中的矩阵中。
Loaded the data as wanted in to a matrix in Octave.
推荐答案
load 通常用于加载octave和matlab二进制文件，但可用于加载像你这样的文本数据。您可以使用 - ascii选项加载数据，但在将文件放入 load 即使启用了 - ascii选项。使用一致的列分隔符即。只是一个标签或逗号，使用完全数字而不是 3850。并且不要使用字符串。
load is usually meant for loading octave and matlab binary files but can be used for loading textual data like yours. You can load your data using the "-ascii" option but you'd have to reformat your file slightly before putting it into load even with the "-ascii" option enabled. Use a consistent column separator ie. just a tab or a comma, use full numbers not 3850. and don't use strings.
然后你可以做这样的事情让它工作
Then you can do something like this to get it to work
DATA = load("-ascii", "auto.txt");
