Hi! I am loading in a pretty large text file, and I want to omit column 1 from reading my data. I'm not excellent at matlab, so I was wondering if anyone had any input? Here is the first few points of the data:
1.00000 0.00635 0.00787 0.43964 -0.08261 0.00528 -0.00278
1.00000 0.00803 0.00775 0.43942 -0.08252 0.00421 -0.00421
1.00000 0.00851 0.00894 0.43985 -0.08276 0.00385 -0.00183
1.00000 0.00827 0.00742 0.43930 -0.08380 0.00308 -0.00238
1.00000 0.00888 0.00641 0.43933 -0.08395 0.00333 -0.00296
1.00000 0.00879 0.00674 0.43997 -0.08438 0.00262 -0.00333
1.00000 0.01123 0.00507 0.44019 -0.08530 0.00098 -0.00317
1.00000 0.01279 0.00406 0.44040 -0.08594 0.00070 -0.00253
(also the preview version is messing with how the data is supposed to show - sorry!) I do not want to include the first column in my data, only columns 2-7. Any suggestions on how to do this? Thanks!

Try:
fid = fonpen( filespec );
cac = textscan( fid, '%*f%f%f%f%f%f%f', 'CollectOutput', true ) ;
sts = fclose;
and see help on &nbsp textscan
