dlmwrite error: Skipping lines, adding garbage values

I have a 455x39 array that I need to append to a text file. When I'm using dlmwrite,

dlmwrite(fileName, arrayName,'delimiter',\t,'-append');

it gives me 454 rows, with an additional garbage row above it. If I use the same command to write this array to a new file, it works correctly. What is going wrong?

Seems to work here w/ R2012b.

1. What release?
2. How was original file created?

Attach your text file and m-file.

So that's my m file for that particular function and the raw data. I did fprintf in the end and solved the issue, but dlmwrite, the way suggested by you gives me an error.

Anyway, the problem is solved with fprintf. Thank you.

The way I suggested works just fine - I tried it several times. You must have used it improperly. If you still want to use the dlmwrite() method or want to know what the error message was about, then give your code for it.

This works fine for me

arrayName = randi(9, 455, 39);
dlmwrite('deleteme.txt', arrayName, 'delimiter','\t','-append');

though I did have to add single quotes around your \t. I ran it twice and there is no garbage row at line 456, between the two sets of data.
