I need a general coding in which we can change function and number of iteration at any time

tol := 0.1e-5; n := 10; x := Array(0 .. n); x[0] := .1; f := proc (x) options operator, arrow; x^2-3 end proc; h := proc (x) options operator, arrow; unapply(diff(f(x), x), x) end proc; for k to n do x[k] := evalf(x[k-1]-f(x[k-1])/h(x[k-1])); if abs(x[k]-x[k-1]) < tol then print("Number of iterations" = k); print("approximate solution" = x[k]); print(f(x[k])); break end if; x[k-1] := x[k] end do; interface(rtablesize = n+1); x(); interface(rtablesize = n); plot([f(p), f(x[k-1])+(p-x[k-1])*h(x[k-1])], p = -1 .. 3, colour = [red, black])

0.1e-5

  

10

  

.1

  

proc (x) options operator, arrow; x^2-3 end proc

  

proc (x) options operator, arrow; unapply(diff(f(x), x), x) end proc

  

Error, (in h) invalid input: diff received .1, which is not valid for its 2nd argument

  

10

  

Array(0 .. 10, {0 = .1}, datatype = anything, storage = rectangular, order = Fortran_order)

  

11
