| convex.bounds {dlm} | R Documentation |
Finds the boundaries of a bounded convex set along a specified
straight line, using a bisection approach. It is mainly intended for
use within arms.
convex.bounds(x, dir, indFunc, ..., tol=1e-07)
x |
A point within the set |
dir |
A vector specifying a direction |
indFunc |
Indicator function of the set |
... |
Parameters passed to indFunc |
tol |
Tolerance |
Uses a bisection algorithm along a line having parametric representation
x + t * dir.
A vector ans of length two. The boundaries of the set are
x + ans[1] * dir and x + ans[2] * dir.
