I installed the Maple Toolbox for MATLAB, I have both Maple 13 & MATLAB r2009b, so when I try to run the command syms I get this:

 syms x y 
??? Error using ==> sym.sym at 164
Attempt to execute SCRIPT maplemex as a function:
/Applications/MATLAB_R2009b.app/toolbox/maple/maplemex.m

Error in ==> syms at 57
	    assignin('caller',varargin{i},sym(varargin{i}));

I don't know what the hell is happening I have been trying to do everything but nothing have worked. I am on Mac OS X 10.6.2. What is going on with this issue?

Thanks in advance.
