Thanks Roger, I have specified it as syms Cell, that ought to know that it is an unknown variable.. will try the symbolic math toolbox though. that should work. 
Can you let me know the exact commands you put in for lambertw fxn, I am having a lill difficulty putting it.

Hello Christopher,

Okay, I think that should work. I was also trying to solve the same thing using lambertw, since this solve answer has errors of order 10^3 from what is expected.
