getAb: Returns augmented matrix representation of edit set.

Description

For a system of linear (in)equations of the form \(Ax \odot b\), \(\odot\in\{<,\leq,=\}\), the matrix \(A|b\) is called the augmented matrix.

Usage

getAb(E)

Value

numeric matrix A|b

Arguments

E

editmatrix

Examples

E <- editmatrix(c( "x+3*y == 2*z"
                 , "x > 2")
                 )
print(E)
                 
# get editrules, useful for storing and maintaining the rules external from your script
as.data.frame(E)
                 
# get coeficient matrix of inequalities
