Loop through files in a folder in matlab
I have a set of days of log files that I need to parse and look at in matlab.
The log files look like this:
LOG_20120509_120002_002.csv
(year)(month)(day)_(hour)(minute)(second)_(log part number)
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
.
I also have another file:
LOG_DATA_20120509_120002.csv
which contains data for the whole hour (different data).
The overall objective is to:
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
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?
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
At first, you must specify your path, the path that your *.csv
files are in there
path = 'f:\project\dataset'
You can change it based on your system.
then,
use dir
function :
files = dir (strcat(path,'\*.csv'))
L = length (files);
for i=1:L
image{i}=csvread(strcat(path,'\',file(i).name));
% process the image in here
end
pwd
also can be used.
