Hi,
I'm trying to access certain parts of a text to process data. The text file has a header and many rows of numbers, starting at lines 13 through 4016 is a two column array. This is comma delimited. It would be nice to track information of this file located in the header but firstly I just want to bring all of these numbers into Matlab for processing. The formats don't change per text file just the numbers.
Thanks for your help, Alex

fid=fopen('file.txt')
out=textscan(fid,'%f %f','HeaderLines',12,'Delimiter',',')
fclose(fid)
M=cell2mat(out)

I figured it out, there is a special function that does all of this hands free.
num = csvread(filename,13,0)
this data is already comma delimited, so I could open it as a txt file without any problems. If there aren't commas it might not be so easy.
