Plots 2 dimensional projections.
lowdisc_proj2d ( u , dimensions )
a nsim x n matrix of doubles, the numbers in the interval [0,1]^n
a p x 1 matrix of floating point integers, dimensions to plot.
Plots the required two dimensionnal projections of u, with size nsim x n, where nsim is the number of simulations and n is the dimension of the space. This function allows to see all the 2 dimensionnal projections of a multivariate vector u.
callf = 1.e2; n = 6; ldseq = "haltonf"; strict = %t; [ evalf , u ] = lowdisc_ldgen ( callf , n , ldseq ); // See all possible projections. lowdisc_proj2d ( u , 1:n ) // See all projections for dimensions 2,3,6. scf(); lowdisc_proj2d ( u , [2,3,6] ) // See projection (3,6) scf(); lowdisc_proj2d ( u , [3,6] ) // In this case, we could also use : scf(); plot( u(:,3) , u(:,6) , "bo" )
