N= $\displaystyle \frac {-2 + \frac {1}{1-W} }{2-\frac {1}{W}} - \frac {L}{P(2-\frac {1}{W}) }$

I was wondering if this could be simplified. W ranges from 0 to 1, P, L, and N are all positive. I'd also like to create a table or a graph of N in terms of P, L or W, given we know the other 2 but I don't know how to do that in MatLab, any tips?.
