Examples

set.seed(123)
y <- array(rnorm(3*3),dim=c(3,3))
dy <- matrix(rnorm(length(y)*2),ncol=2)
dx <- crossprod(matrix(rnorm(ncol(dy)*100),nrow=100))
obj0 <- madness(val=y,vtag='y',xtag='x',dvdx=dy,varx=dx)
z <- array(rnorm(3*3),dim=c(3,3))

anobj <- + obj0
anobj <- - obj0
anobj <- 6 - obj0
anobj <- 1 + obj0
anobj <- obj0 - 3
anobj <- z + obj0 
anobj <- obj0 - z

obj1 <- obj0 ^ 2
anobj <- (0.3 * obj0) + (5.1 * obj1)

anobj <- 2 ^ obj0
anobj <- obj1 ^ obj0
anobj <- obj1 / obj0
anobj <- z / obj0
