Is it a polynomial, or an equation involving tan(x) and exp(x)?
Have you looked at fzero()?
For example, if you have the equation
y = tan(x) and you want find a root near 3
fzero(@tan,3)
Gives you the root at pi.

fzero(@(x)exp(x)+x-10,0)
fzero(@(x)tan(x)-x-.01,0)
fzero(@(x)tan(x)-x-.01,pi)

then fzero will work as I suggested.
fzero(@(x) exp(x)+x-10,0)
says "Find the zeros of exp(x)+x-10 near 0
