如何在Matlab中读取多个日志文件

Question

I would like to open multiple log files, and concatenate them so that they make one big log file, from which I can then extract the information I need.

I would like matlab to open as many files, as there are in my folder, based on the name including a certain string.

here is my code so far:

pilotfiles = dir (['*PILOT*.log'])

for fil=1:length(pilotfiles)
    files{fil}=pilotfiles(fil).name;
end;
   files=char(files);

for fil = 1:length (files (:,1));
    clear logs;
    file_name = files (fil,:);
    noofColumns = 45;
    cs = repmat('%s', 1, noofColumns);
    fileID = fopen(deblank(file_name));
    logs = textscan(fileID,cs); 
    biglog = horzcat (logs {:}); 
    fclose (fileID);    
end

Of course, I would not be asking this question if the code worked.

file_name correctly returns names of all my files, 'logs' seems to read the contents of each of the files, but then my 'biglog' only contains the contents of the last log file .

Anybody has any ideas where am I making the mistake?

NOTE: I am working on a MAC, this code is based on a code, which has worked on a PC

Answer 1

pilotfiles=dir('*PILOT*.log');
pilotfiles=pilotfiles(3:end);
N=numel(pilotfiles);
logs=cell(1,N);
cs=repmat('%s',1,45);
for i=1:N
    fid=fopen(fullfile(pilotfiles(i).folder,pilotfiles(i).name));
    logs{i}=textscan(fid,cs);
    logs{i}=[logs{i}{:}];
    fclose(fid);
end
biglog=[logs{:}];

Cheers.
