MATLAB: .csv Date and Time assigned Data Import

Hi George,

If you're using R2016b you can import this directly, but it will take a little bit of configuration The following should work:

opts = detectImportOptions(yourfilename,'Delimiter',';') 
opts.VariableTypes = {'datetime','double','double','double','double'};
opts = setvaropts(opts,1,'InputFormat','yyyy/MM/DD HH:mm:ss,SSS');
opts = setvaropts(opts,2:5,'DecimalSeparator',',');
T = readtable(yourfilename,opts)

MATLAB: Import .csv Data and assemble structure array

First list all files in your directory. This will get you started:

dirContent = dir('C:\Users\blah\blah\blah');
contentList = {dirContent.name};

Then loop through each file ID number and use regexp or strfind to identify matching files.

fileIDs = {'1111', '2222', '3333'};  %from your meta file 
for i = 1:length(fileIDs)
    matches = regexp(contentList, sprintf('%s*.csv', fileIDs{i}), 'match');
    selectedFiles = matches{~cellfun(@isempty, matches)};
    % Now you can import data from selectedFiles{:} here
end

My code assumes your fileIDs will be strings; if that's not the case you'll need to make small changes. You may also need to adapt the regular expression to your filenames. This has not been tested and represents a basic method you'll likely need to adapt to your needs.
