Elementwise Scalar Optimization (scipy.optimize.elementwise)

This module provides a collection of functions for root finding and minimization of scalar, real-valued functions of one variable. Unlike their counterparts in the base scipy.optimize namespace, these functions work elementwise, enabling the solution of many related problems in an efficient, vectorized call. Furthermore, when environment variable SCIPY_ARRAY_API=1, these functions can accept non-NumPy, array API standard compatible arrays and perform all calculations using the corresponding array library (e.g. PyTorch, JAX, CuPy).

Root finding

find_root(f, init, /, *[, args, tolerances, ...])	Find the root of a monotonic, real-valued function of a real variable.
bracket_root(f, xl0[, xr0, xmin, xmax, ...])	Bracket the root of a monotonic, real-valued function of a real variable.

Minimization

find_minimum(f, init, /, *[, args, ...])	Find the minimum of an unimodal, real-valued function of a real variable.
bracket_minimum(f, xm0, *[, xl0, xr0, xmin, ...])	Bracket the minimum of a unimodal, real-valued function of a real variable.
