NCL'ers
I need to write a function that uses the Newton-Raphson iterative method to solve a mathematical function,
e.g. find x for which f(x) = 0, which is solved iteratively by the Newton Raphson method thus
do while (dx.le.del) ;where 'del' is some acceptable level of convergence e.g. 0.01
x1 = x0 + f(x0)/ f'(x0)
dx = (x1-x0)^2/x0^2
x0 = x1
end do
Is it possible to define a function with arguments that call other functions, i.e.
function Newt-Rap(f, fdash, x0)
If not, is there another way of writing a generic subroutine that can reference other functions?
Will
