Hi,

I'm fairly new to Matlab and have v4.0.  A typical data file for me contains
some strings for documentation/plot labeling, and some data.  I've tried
the [A,count] = fscanf(fid,'format',size)  routine for reading strings, 
but it leaves something to be desired.  With no size argument, 
it tries to read to the end of file.  If a size argument is used
then that is the number of whitespace seperated groups of characters are 
read (ie. words).  Isn't there a way to read a newline terminated string?
Am I missing something?  Is there a better way to read strings?

If anyone has any helpful hints I would be much obliged.  If there is
interest I will post a summary.  Thanks, -jim

Try "fgets" or "fgetl".  If you need to extract pieces from the line
you can do that with "sscanf".  This is what I've been doing and it
works ... but, as always, there may be a better way.
