bisection {cmna} | R Documentation |
Use the bisection method to find real roots
bisection(f, a, b, tol = 0.001, m = 100)
f |
function to locate a root for |
a |
the a bound of the search region |
b |
the b bound of the search region |
tol |
the error tolerance |
m |
the maximum number of iterations |
The bisection method functions by repeatedly halving the interval
between a
and b
and will return when the
interval between them is less than tol
, the error tolerance.
However, this implementation also stops if after m
iterations.
