  1. * nsolve                                              external
  2. nsolve(cos(x)=x, x)
  3. It numerically solves equation with default initial x0=1.
  4.  
  5. nsolve(x^2=1, x,x0)
  6. It numerically solves the equation with initial x0.
  7. It only gives a root near x0 if equation has multi roots.
  8. See also: solve, dsolve.
  9. e.g. nsolve(sin(x)=0, x,3) gives 3.14.
