Convert support of a mu/phi/cov etc. to and from obsGrid and workGrid

Description

Convert the support of a given function 1-D or 2-D function from fromGrid to toGrid. Both grids need to be sorted. This is an interpolation/convenience function.

Usage

ConvertSupport(
  fromGrid,
  toGrid,
  mu = NULL,
  Cov = NULL,
  phi = NULL,
  isCrossCov = FALSE
)

Arguments

fromGrid	vector of points with input grid to interpolate from
toGrid	vector of points with the target grid to interpolate on
mu	any vector of function to be interpolated
Cov	a square matrix supported on fromGrid * fromGrid, to be interpolated to toGrid * toGrid.
phi	any matrix, each column containing a function to be interpolated
isCrossCov	logical, indicating whether the input covariance is a cross-covariance. If so then the output is not made symmetric.
