Hi guys
my files are organised as such:
Engine\Vehicle\Date\data.csv
files for each vehicle are organised into days.
I want to be able to run my script from one location without having to copy it into each folder that I want to use it. This is for data analysis so the file names and subfolder names change regularly each day. the folder name stays the same however.
The script that I use lives in a different directory.
Currently I have been able to add the files to the script path with
addpath(genpath('Engine'))

Hi,
what about the following procedure:
theDates = dir('.\Engine\Vehicle');
for iDate = 1:length(theDates)
if theDates(i).isdir
data = csvread(fullfile(pwd, 'Engine', theDates(iDate).name, 'data.csv'));
end
end

Hi
Sorry for the late reply, when it comes to executing the file is there a way to choose a range, so if a drop box says choose date, you would be able to enter a range such as
01/08/2012-07/08/2012

Hi,
you could do something like
startDate = datenum('01/08/2012');
endDate = datenum('07/07/2012');
theDateNums = datenum({theDates.name});
% now choose:
idx = theDateNums>=startDate & theDateNums<=endDate;
theDates = theDates(idx);
% continue processing all files of theDates

Several examples are in the FAQ: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F
If you want to interactively select files based on the date, use uigetfile() and then you use the icon in the dialog box to show details, one of which will be the date. You can also sort them there.
