is.positive.definite

Returns <code>TRUE</code> if and only if a matrix is positive definite.

array

Performs Bayesian calibration of computer models as per
Kennedy and O'Hagan 2001.  The package includes routines to find the
hyperparameters and parameters; see the help page for stage1() for a
worked example using the toy dataset.  A tutorial is provided in the
calex.Rnw vignette; and a suite of especially simple one dimensional
examples appears in inst/doc/one.dim/.
