In Irstea/cpgsR: Uniform sampling in convex polytope

Description

getBoundParam Computes the possible bounds for a parameter p of a polytope defined by+A.x<=b and C.x=v

Usage

getBoundParam(A, b, p, C = NULL, v = NULL)

Arguments

A	the matrix of inequality A.x<=b
b	the vector A.x<=b
p	the index of the parameter for which the bounds should be computed
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 vector with lower bounds and upper bounds

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 <- getBoundParam(A,b,1)
