I have a text file (a) contains words and numbers and colons. I would like to use the fscan and the fread function to get a time. However, the time is like this 2:30:20
I wonder, how can I do that such that there are cono(:) marks in between.
B=fread(a,time,'uint16');
I think the problem is in the uint16, but I don't know how to solve that.
Thanks in advance for your help

Looks like you are getting the time as "Duration" class, Try one of these as required to fetch hours or seconds or minutes or milliseconds etc.
milliseconds(time) or
seconds(time) or
hours(time) or
minutes(time)
..........etc, provided time has class 'duration' you may check by typing class(time)

Please attach the file itself, not a text copy. Use the paperclip icon to attach it to a comment.

Dear Rik, thank you very much for your help, and sorry for my late response I was so busy.
Actually, I added the following code to the original one and it works :
A=regexp(text,'Time');
B=regexp(text,'Height');
L=B-A(1);
if L==16
C=strfind(text,'Time');
time_hour=str2num(text(C(1)+7:strfind(text,'Height')-8));
time_min=str2num(text(C(1)+10:strfind(text,'Height')-5));
time_hour=str2num(text(C(1)+13:strfind(text,'Height')-3));
time=60*60*time_hour+60*time_min+time_sec;
end
% % I also changed the length L based on the time and it worked
