This function is based on the Gaussian Landscape Generator by Bo Yuan and Marcus Gallagher.
It randomly evaluates one or several points in several Gaussian Landscapes at once, as created by
matrix of sample sites, containing one point in each row.
list of lists (one for each landscape) of values defining the Gaussian Landscape, created by
returns a list, with the following items:
value vector of values from each landscape.
components value of each component (will be NA)
