In Irstea/cpgsR: Uniform sampling in convex polytope

Description

getAllBoundsParam Computes the possible bounds for all parameters of a polytope defined by A.x<=b and C.x=v

Usage

getAllBoundsParam(A, b, C = NULL, v = NULL)

Arguments

A	the matrix of inequality A.x<=b
b	the vector A.x<=b
C	the matrix of equality C.x=v (default NULL for no equality)
v	the vector of equality C.x=v (default NULL for no equality

Value

a datrame with first column corresponding to colnames(A), and corresponding lower bounds (column 2) and upper bounds (column 3)

Examples

n <- 20
A1 <- -diag(n)
b1 <- as.matrix(rep(0,n))
A2 <- diag(n)
b2 <- as.matrix(rep(1,n))
A <- rbind(A1,A2)
b <- rbind(b1,b2)
X0 <- getAllBoundsParam(A,b)
