Extracting data from txt file
显示 更早的评论
I have a textfile that looks like this:
Site 4911445 PLUS at KG.LINTANG, PERAK
Date,Time,Flow m3/s
01/07/1960,06:00:00,17.81
01/07/1960,07:00:00,17.81
01/07/1960,08:00:00,17.81
01/07/1960,09:00:00,17.81
I'd like to create a matrix with in the first column the Date, second column the Time and third column the Flow. How to program that again?
fname = 'name.txt';
fid=fopen(fname,'r');
A = fscanf(fid, format)
What to use for the format?
Thanks heaps, Marijn

It is a good attempt that you made here with FOPEN and FSCANF; we can discuss the format if you want, but I would recommend using TEXTREAD in this case, which would simplify the process:
[dateString, timeString, flow] = textread('myFile.txt', '%s %s %f', ...
'delimiter', ',', 'headerlines', 2)
So here you have a one shot operation that opens/reads/formats the whole file, whereas you would have to read the file line by line and build arrays by yourself if you were using FSCANF.
