path command in MATAB

path command in MATAB

I'm having difficulty utilising the l1-magic and WaveLab matlab toolboxes
(these are 3rd party). My main difficulty is loading the solvers etc with
the path command.
I've unpacked the respective files into the MATLAB\R2012a\toolbox folder
and added these to the path via File->Set Path.
My scripts keep on failing on the
path(path, './Optimization')
or
path(path, './Data')
lines and won't recognise any functions contained therein.
Is there anyhting I've missed out?
