Use golden section search to find local extrema
1 2 3 | goldsectmin(f, a, b, tol = 0.001, m = 100)
goldsectmax(f, a, b, tol = 0.001, m = 100)
|
f |
function to integrate |
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 golden section search method functions by repeatedly dividing 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 stop if after m
iterations.
the x
value of the minimum found
