- To do this, make a second text file with the first 15 or so representative rows of your current one.
- Right click on it from the current folder browser and select Import Data, or click on Import Data on the Home Tab.
- Make any selections you have to with regards to delimeters/formats/etc.
- Then underneath the green check for import data, select the drop down menu "Generate Function". # Save this file and then use it to import the original full size file.
Using textscan for large .txt data files

I have a .txt file, separated by tabs, with about 150MB and 2 or 3 columns. Import data does not seem to work and I wanted to use the textscan function, since I believe will be the most effective. Is there any special (simple and fast) way to do this? I am new at matlab. Thank you in advance!

I would use the Import Tool to generate a function that calls textscan.
