Find roots using Newton-Raphson algorithm
find root of a function using the Newton Raphson algorithm.
newtonRaphson(f, df, start = 0, atol = 1e-04, rtol = 1e-04, maxit = 10000, ...)
f |
a numeric valued function from a single numeric argument. |
df |
the derivative of 'f'. |
start |
numerical value. The initial position for the Newton Raphson iteration. |
atol |
numeric value. The absolute tolerence for finding a root. |
rtol |
numeric value. The relative tolerence for finding a root. |
maxit |
an integer value. The maximal number of iterations. |
... |
additional parameters to be passed to 'f'. |
a numeric value, the root.
