example

 If you want 2 roots of the function:  f(X) = EXP(0.4*X)-0.4*X-9

 X=[0;0]                     ! define dummy vector with 2 elements
 FZERO X EXP(0.4*X)-0.4*X-9  ! results reported below
 Root#   1 =  6.0921D+00 after   10 iterations
 Root#   2 = -2.2500D+01 after   12 iterations

 If you initialize X differently, the number of iterations will change:

 X=[10;-20]
 FZERO X EXP(0.4*X)-0.4*X-9   results in:
 Root#   1 =  6.0921D+00 after    8 iterations
 Root#   2 = -2.2500D+01 after    6 iterations

 In either case, the vector X will be [6.09209924;-22.4996914]
