Note: You can also numerically solve equations using the context menus.
See Solving Equations and Inequations (page 78).
It is recommended that you verify the solutions returned by the fsolve com-
mand. For details, see Working with Solutions (page 86).
Multiple Equations To solve multiple equations, specify them as a set. The
fsolve command solves for all unknowns.
>
Univariate Polynomial Equations In general, the fsolve command finds
one solution. However, for a univariate polynomial equation, the fsolve
command returns all real roots.
