Please find the attachment.

The data is already tabular, so just use readtable instead.

jonas why the possible answer is in comment?

Apart from the low effort put into my comment, I did not feel that it addressed the actual question, which seems to be specifically about textscan. I made the post shortly after the question was posted, so I was hoping for a quick reply after which I could expand my comment into an actual answer. Perhaps I should have phrased my comment in a different way.

You can use readtable since the data is tabular.

T = readtable('AE33_AE33-S02-00184_20170102.dat','headerlines',8)

...gave me a 71 column table. Some of your headers are not valid variable names so I did not import them at all.

If you insist on using textscan, then

fid = fopen('AE33_AE33-S02-00184_20170102.dat')
out = textscan(fid,['%{yyyy/MM/dd}D %{hh:mm:ss}T',repmat('%f',1,69)],'headerlines',9)
fclose(fid)

Odd. I suspect you are using an ancient release that cannot parse the duration format? You can always import the dates as strings. Try this:

fid = fopen('AE33_AE33-S02-00184_20170102.dat')
out = textscan(fid,['%s%s',repmat('%f',1,69)],'headerlines',9)
fclose(fid)
