Question

I am trying to read a data file but I have an older version of Matlab that does not include textscan. I am trying to use fscanf but I am unable to figure out how to read the second element which is time format. The txt data looks like this:

20120502,16:30:00,1397.5,1397.5,1397.0,1397.5,1283
20120502,16:32:00,1397.25,1397.5,1397.0,1397.0,582

I have tried this, with different attempts at figuring out the 2nd column which is the time vector, but I am not having any luck.

fid = fopen('C:\matlab\data\GLOBEX.txt','r');  
[c] = fscanf(fid, '%f %s %f %f %f %f %f');  

Thanks

Try the following:

[c] = fscanf(fid, '%f,%d:%d:%d,%f,%f,%f,%f,%f');  
c = reshape(c, 9, length(c)/9)';

Now you have hours, minutes, and seconds in columns 2, 3, and 4.
