In Irstea/cpgsR: Uniform sampling in convex polytope

Description

plotPolytope2D polt the possible values of a multimensional convex polytope by A.x<=b and C.x=v for 2 dimensions

Usage

plotPolytope2D(A, b, C = NULL, v = NULL, params = c(1, 2))

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
params	a vector of length 2 corresponding to the index of the parameters

Value

a ggplot

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 <- plotPolytope2D(A,b)
