How can I find solutions included in an interval ??

I am trying to solve an equation of one unknown Z using fsolve.
Let us say that the value of the guess for Z is 610 and that I am using the writing: fsolve(@eqns,610).
Which writing should I use to find only the solutions Z which are included in the interval [600 670] ??

fzero(@eqns, [600 670])
Notice that is fzero, not fsolve.
Warning: in order for fzero to work on an interval, the equation evaluated at the two endpoints must have different signs.

Thank you very much Walter Roberson.
Really the problem of sign difference is a big problem.
Is there any solution to that ???
