The corners of the hypercube are linearly interpolated. By default, \code{dimnames(a)} is taken to contain the coordinate values for each point in \code{a}. This can be overridden using \code{adims}. If \code{method=="constant"}, the value of the ``lower left'' corner of the hypercube is returned.}\author{Friedrich Leisch}\seealso{\code{\link{approx}}, \code{\link{spline}}}\examples{x <- seq(0,3,0.2)z <- outer(x,x, function(x,y) sin(x*y))dimnames(z) <- list(x,x)sin(1.1*2.1)interpolate(c(1.1, 2.1),z)}\keyword{arith}\keyword{multivariate}
