Function `linmin`

$\begin{boxedminipage}{\textwidth} \begin{verbatim}l = linmin(x0,xdir,y,epsilon, & func)\end{verbatim} \end{boxedminipage}$

Smart line minimiser, adapted from Numerical Recipes. The objective function is func.

x0 -- real(dp), dimension(:)

Starting position

xdir -- real(dp), dimension(:)

Direction of gradient at x0

y -- real(dp), dimension(:)

Finishing position returned in y after linmin

epsilon -- real(dp)

Initial step size

Function func(x) -- real(dp)

x -- real(dp), dimension(:)

Return value -- integer
