MATLAB: Concatenate data using fgets

You are closing the file in the loop. close the file after the loop. I assume the below should work.

function read_datapattern(filename)
fid = fopen(filename,'rt');
if fid < 0
  error('error opening file %s\n\n',filename);
end
pattern = fgets(fid);
for n = 1:32767
  nextline = fgets(fid);
  pattern = strcat(pattern, nextline);
fprintf(pattern);
fprintf('\n');
end
fclose(fid);

MATLAB: Issue with data format when using textscan()

The format should be all lower case for duration.

%{hh:mm:ss}T

However, the data appears to be delimited as semicolon. You'd have more luck with readtable:

opts = detectImportOptions('D:\SI010118.txt')
opts = setvartype(opts,1,'datetime')
opts = setvaropts(opts,1,'InputFormat','dd.MM.uuuu HH:mm:ss')
readtable('D:\SI010118.txt',opts)
