textread not working with .text file

3 views (last 30 days)
Before I try to apply textread to the .txt file, I have already split up the file from a large text file to smaller text files using a script which is successful in its execution and uses functions fopen, fgetl.
Large Text File -> Small Text File 1, Small Text File 2, Small Text File 3
Output of Small Text File 1:
Run Lat Long Time
2 1 13 3
2 3 3 3
3 3 5 12
From the split up text file -- small text file 1 -- which is in column format, I apply textread and returns a mixture of random (scattered) data from the text file (random sample of data from col2 and col3).
In the code: the function is the basic:
[col1 col2] = textread('smallfile.txt', '%d %d');
Output Return: 3 12 13 5
Not what is in Col1 = 2 2 3
I have tried to fix it by checking ANSI encoding and applying rt in my opening function. But no success.
Thanks,
Amanda

I have update the question to be clearer. I'm trying to get the data in columns for plotting.

textread() is going to read all the data on the line, not only as many columns as you provide %d for.

You could use:
[A,' ', 1] = importdata('myFile.txt);
%And the variables you want:
col1 = A.data(:,1);
col2 = A.data(:,2);
For more info
help importdata
And if you need low level routine:
help fscanf
Cheers!

Look inside A.textdata, all text data should be in there. More details in:
help importdata
