Thx. Dnb,
The file i have is a csv file which has 25 description in it and reads like
1998-12-24T03:47:00.000,1998-12-24T04:08:00.000,1998-12-24T03:48:05.698, 917,54, 23.3........folowed by data.
i am reading the file by putting:
header = textscan(fid, '%[^,],%[^,],%4d-%2.2d-%2.2dT%2.2d:%2.2d:%06.3f,%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%f,%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,],%[^,\r\n]', 1);
and than writing only the 3rd decription to output.
by:
for i=3;
occtime=header{i};
end;
formatSpec = '%d-%2.2d-%2.2dT%2.2d:%2.2d:%06.3f';
fprintf(formatSpec,occtime);
but t is just printing 1998 in place of 1998-12-24T03:48:05.698
pl. comment
