How can I read a text file as fixed width columns?

Hello,

I have a traffic cards with information about traffic every 15 minutes, over one year I will have 2500 rows in every card. each row must be divided into 25 columns with a fixed width as shown in the next line.

Column widths: 1 2 6 1 1 2 2 2 2 4 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5 how can I do this in matlab please?

What is a traffic card? What exactly is your input. Text files?

cw=[1 2 6 1 1 2 2 2 2 4 5 5 5 5 5 5 5 5 5 5 5 5 5 5 5];
fmt=sprintf('%%%dd',cw);
% file open preamble code here for opening file, return valid fid
data=cell2mat(textscan(fid,fmt,'collectoutput',1));

Above presumes all are integer fields, if data does include floating point values fix up format fields to match.

PS: Do not use user ids for tags in future...
