Module scid.nonlinear
Functions related to the solving of nonlinear equations, i.e. finding
roots of nonlinear functions.
Functions
| Name | Description |
bisect(f, predicate, xTrue, xFalse, xTolerance, maxIterations)
|
Use bisection to find the point where the given predicate goes from
returning false to returning true.
|
bracketRoot(f, x0, scale, xMin, xMax)
|
Bracket a root of the function f.
|
bracketRoots(f, a, b, nIntervals, buffer)
|
Divides the interval [a,b] into the given number of equal-sized
subintervals,
checks whether any of the subintervals bracket a root, and returns
the ones that do, together with the function values at those points.
|
findRoot(f, guess, epsRel, maxFuncEvals, buffer)
|
Searches for a root of N functions of N variables using a variant
of the Powell Hybrid Method (the HYBRD routine from MINPACK).
|
findRoot(f, x0, scale, xMin, xMax, precision)
|
Find a root of the function f.
|
findRoots(f, a, b, nIntervals, buffer)
|
Uses bracketRoots() to divide the interval [a,b] into subintervals
and check which ones bracket roots. Then, findRoot() is applied
to each bracketing interval, and an array containing the roots
is returned.
