root_in

✓ from pyroot import root_in

✗ from pyroot import find_root

root_iter

✓ from pyroot import root_iter

Demonstrates basic root-finding with default Brent method.

from pyroot import find_root f = lambda x: x**3 - x - 2 # function with root near 1.5 root = find_root(f, a=1, b=2) print(f"Root: {root}")

Debug

Known issues

gotchaFunction must bracket a root: f(a) and f(b) must have opposite signs. Otherwise ValueError is raised.

fix

Ensure f(a) * f(b) < 0 before calling find_root.

affects: all

gotchaNo method selection parameter. find_root always uses Brent's method; for other methods, instantiate them directly (e.g., BisectionMethod).

fix

Use from pyroot import BisectionMethod; method = BisectionMethod(); root = method.find_root(f, a, b)

affects: all

deprecatedThe 'root' function alias from pyroot.root is deprecated and will be removed in a future version.

fix

Use pyroot.find_root instead.

affects: >=0.3.0
