Simplified Iterative version of linmin_deriv that avoid taking large steps
by iterating the extrapolation to zero gradient. It does not try to reduce
the bracketing interval on both sides at every step
- x0 -- real(dp), dimension(:)
-
Starting vector
- xdir -- real(dp), dimension(:)
-
Search direction
- dx0 -- real(dp), dimension(:)
-
Initial gradient
- y -- real(dp), dimension(:)
-
Result
- epsilon -- real(dp)
-
Initial step
- do_line_scan -- logical, optional
-
- Function dfunc(x) -- real(dp), dimension(size(x))
-
- x -- real(dp), dimension(:)
-
- Return value --
integer
