hello i have text file . i am trying to read it read it but not getting the results.

endarcfmt = ['%s', repmat('%f64',1,4)]
fid = fopen('half.txt','r');
dc = textscan(fid, arcfmt, 'HeaderLines', 1, 'Delimiter', '\t', 'EmptyValue', uint8(0), 'CollectOutput', 1)
fclose(fid);

It appears to be

dc = textscan(fid, arcfmt, 'HeaderLines', 1, 'Delimiter', '\t', 'MultipleDelimsAsOne', true, 'CollectOutput', 1);

This will only work if there are no missing column entries. If there are missing column entries then it gets complicated to try to figure out when the multiple tabs are there to make things pretty, and when there are there to indicate that the value is not present.

am not getting the result when am modifying this code can you guide me where i am wrong.

clc
clear all
fid = fopen('hhh.txt','r');
dc = textscan(fid, '%s %f %f %f', 'HeaderLines', 1, 'Delimiter', '\t', 'MultipleDelimsAsOne', true, 'CollectOutput', 1);
fclose(fid);
celldisp(dc)
arc_rows = dc{2}
arc_xdrid = dc{1};
acctfmt = repmat('%u64', 1, 3);
fid = fopen('gaoxiaotest2.txt', 'rt')
for part = 1 : 9
  %we read multiple times to account for bugs in the file
ac{part} = textscan(fid, acctfmt, 'HeaderLines', 1, 'Delimiter', ',', 'EmptyValue', uint8(0), 'CollectOutput', 1);
end
fclose(fid);

  arc_MSISDN{k} = temp{1};    %does not make sense as a double!
  rt = temp{2};
  et = temp{3};
  arc_RequestTime{k} = rt;
  arc_RequestTime_datenum = rt / 1000 / 86400 + datenum('01-Jan-1970');
  arc_RequestTime_datetime = datetime(rt/1000, 'ConvertFrom', 'posixtime');
  arc_EndTime{k} = et;
  arc_EndTime_datenum{k} = et / 1000 / 86400 + datenum('01-Jan-1970');
  arc_EndTime_datetime{k} = datetime(et/1000, 'ConvertFrom', 'posixtime');
  fclose(fid);
end

you probably do not need all three forms of the times that I create here. arc_RequestTime and arc_EndTime are the values exactly as read in. arc_RequestTime_datenum and arc_EndTime_datenum are the values read in and converted to serial date numbers, which are the older method of representing time in MATLAB (and sometimes still more convenient.) arc_RequestTime_datetime and arc_EndTime_time are in the newer datetime time representation format. Note: the datetime forms probably take into account leap seconds and timezones relative to you, where the datenum do not.
