ranges {lintools} | R Documentation |
Derive variable ranges from linear restrictions
Description
Gaussian and/or Fourier-Motzkin elimination is used
to derive upper and lower limits implied by a system of (in)equations.
Usage
ranges(A, b, neq = nrow(A), nleq = 0, eps = 1e-08)
Arguments
A |
[numeric] Matrix
|
b |
[numeric] vector
|
neq |
[numeric ] The first neq rows in A and
b are treated as linear equalities.
|
nleq |
[numeric ] The nleq rows after neq are treated as
inequations of the form a.x<=b . All remaining rows are treated as strict inequations
of the form a.x<b .
|
eps |
[numeric] Coefficients with absolute value <= eps are treated as zero.
using Fourier-Motzkin elimination.
