Problem with fzero to solve transcendental equation

I am trying to solve a transcendental equation in x.

k=8.617*10^(05);
Vd3=-48.8;
Vd2=-.18;
fun=@(x) 1-exp((-exp(1)*Vd3)/(k*x))-2+2*exp*((-exp(1)*Vd2)/(k*x));
x0=3;
z=fzero(fun,x0)

I keep getting the error "not enough input arguments".

Hi Nihal,

in the function definition, try deleting the * following the second incidence of 'exp'.
