normalize {editrules}

Normalizes an editmatrix

Description

An set of linear edits of the form {\bf a}\cdot{\bf x}\odot b with is called normalized when all \odot\in\{==,\leq,<\}

Usage

normalize(E)

Arguments

E

editmatrix

Value

If E was normalized, the original editmatrix is returned, otherwise a new normalized editmatrix will be returned

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
getA(E)

# get augmented matrix of linear edit set
getAb(E)

# get constants of inequalities (i.e. c(0, 2))                
getb(E)

# get operators of inequalities (i.e. c("==",">"))
getOps(E)

# get variables of inequalities (i.e. c("x","y","z"))
getVars(E)
