From: Hu Le on 4 Aug 2010 18:26 Hello! i'm very new to Matlab and need some help. I have a text file that looks something like this: $KEEP,16 $REMOVE,20 $KEEP,17 $REMOVE,201 $KEEP,12 $REMOVE,2012 I'm having trouble creating a Matlab script that will allow me to read from the above text file and generate another text file that looks something like this: $KEEP,16 $KEEP,17 $KEEP,12 Basically, preserve only the lines with the word "KEEP" in it and remove the rest (eg. $REMOVE... and break line) My pseudo code looks something like this: fid = fopen('file.txt') t = fread(fid, '*char')' if strfind(t, 'GPGGA') fwrite (fout, t) end fclose('all')
