setiter_root

subroutine setiter_root(iter)

Description:

Allows to alter the maximum number of iterations of the root-finder fzero, if you feel that the default number of 200 iterations is not enough for solving your problem.

Input arguments:

• integer :: iter
  A scalar value indicating the new number of iterations. Note that iter needs to be strictly greater than 0, otherwise the subroutine will throw an error message.
