MATLAB: How to put big text into an array

arraydatatext;

Hi all,

I have a big text (app 100k lines) right now and I wish to put every line as an array… could someone help?

201403 0.000 8.333 0.00 0.00

201403 0.000 8.333 0.00 0.04

So this is one of the lines of my text, and I wish to sort it with a loop as an array like

2014 03 0.000 8.333 0.00 0.00

2014 03 0.000 8.333 0.00 0.04

Can anybody help please?

Thanks!

Though I do not quite understand what you mean by 'sort it with a loop', a good place to start with would be the Import Tool. You should be able to bring in your data into MATLAB and then manipulate it as you please. It also lets you generate code that captures the workflow you followed in the Import Tool and makes it reusable.
