MATLAB: Problems writing a function

absexpplot

Hi all, I'm trying to write a function, but I have some problems, this is the script:
    exp((abs((x+2)*(x-3))/((x+3)*(x-2))))
But Matlab shows me an error:
Error using  * 
Inner matrix dimensions must agree.
So I changed all with .*( what is the difference? ) The plot shows me a straight line at 2,42 (as if I only copy the function on matlab command window), but If I copy the function on wolfram site, the result is as I expect. Why? Thanks in advance, Alessandro

   exp((abs((x+2).*(x-3))./((x+3).*(x-2))))
