Use textscan() instead of fscanf() .

Also, you need to open the correct file name. And you need to fclose(fid)

MATLAB: How to read .dat file using fopen?

fmt = ['%{YYYY/MM/dd}D %{HH:mm:ss}D', repmat('%f', 1, 71)];
fbc = fopen('AE33.dat', 'rt', 'n', 'UTF8');
BC = textscan(fbc, fmt, 'HeaderLines', 7, 'CollectOutput', true);
fclose(fbc);
dt = BC{1}+(BC{2}-dateshift(BC{2},'start','day'));
dt.Format = 'default';
numbers = BC{3};

Now dt is a vector of datetimes read in from the first two columns of the lines, and numbers is a numeric array with 71 columns representing the data on each line after the date/time entries.

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)
