Hi.  OK, I've downloaded Clawpack to my Mac and it seems to run.  Yea! 
:)  When I open Octave to plot an example solution using the m-file 
plotclaw1.m, however, I get

octave:1> plotclaw1
error: `plotclaw1' undefined near line 1 column 1

Now, in the Clawpack manual, it says that to use Matlab to view 
results, "download the directory  claw/matlab  and then set the 
environment variable

     unix> setenv MATLABPATH ".:\$CLAW/matlab"

before starting Matlab, in order to add this directory to your MATLAB 
search path.  This directory contains the routines plotclaw1.m and...."

I have the directory  claw/matlab  with the m-file plotclaw1.m, but 
Octave can't find it.  How do I set up Octave to know to look for files 
in  claw/matlab?  I'm using bash, if that makes a difference.

Thanks.

---John.
