For the version of leasqr I have "verbose" is a global variable that  
defaults to 0 if not specified before calling leasqr.

When I type

from the console, I get

Please (1) re-start Octave and type "whos verbose", then (2) run your  
script, and type "whos verbose" again.

In the first instance, "whos verbose" should not produce anything. If  
you get a description, you likely have that variable set in your  
octaverc file.

If verbose exists in the last instance and is set to 1 (true), then  
either your script is setting it, or your leasqr.m file has been  
modified.

If verbose does not exist in the second instance, or it is set false,  
you may have an old version of leasqr.m or your local version may have  
been modified.
