"%*%"(x, y)
crossprod(x, y = NULL, ...)
"crossprod"(x, y)

"crossprod"(x, y)
"crossprod"(x, y)
tcrossprod(x, y = NULL, ...)
"tcrossprod"(x, y)
"tcrossprod"(x, y)
"tcrossprod"(x, y)
"tcrossprod"(x, y)

Arguments

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 %*% obj0
anobj <- z %*% obj0
anobj <- crossprod(obj0)
anobj <- crossprod(obj0,z)
anobj <- tcrossprod(obj0,obj0)
# NYI: 
# anobj <- obj0 %x% obj0
