循环遍历matlab中文件夹中的文件 [英] Loop through files in a folder in matlab

问题描述

我有一组日志文件需要在 matlab 中解析和查看.

I have a set of days of log files that I need to parse and look at in matlab.

日志文件如下所示:

LOG_20120509_120002_002.csv
(year)(month)(day)_(hour)(minute)(second)_(log part number)

日志每小时递增一次，但有时秒数会减少一到两秒(每小时)，这意味着我需要忽略他们说要做什么 loadcsv.

The logs increment hourly, but sometimes the seconds are one or two seconds off (per hour) which means i need to ignore what they say to do loadcsv.

我还有另一个文件:

LOG_DATA_20120509_120002.csv

包含整个小时的数据(不同的数据).

which contains data for the whole hour (different data).

总体目标是:

 loop through each day 
     loop through each hour
         read in LOG_DATA for whole hour
         loop through each segment
             read in LOG for each segment
                 compile a table of all the data

我想问题是，如果一天中的分钟不同，我该如何忽略它们?我怀疑它将通过循环遍历文件夹中的所有文件，在这种情况下我该怎么做?

I guess the question is then, how do i ignore the minutes of the day if they are different? I suspect it will be by looping through all the files in the folder, in which case how do i do that?

推荐答案

遍历文件夹中的所有文件相对容易:

Looping through all the files in the folder is relatively easy:

files = dir('*.csv');
for file = files'
    csv = load(file.name);
    % Do some stuff
end
