Description

Gradient for bilinear interpolation

Usage

bilinearGrad(loc, cov_list)

Arguments

loc

Point at which the gradient should be evaluated (2d vector)

cov_list

List of J (number of covariates) "raster like" elements. A raster like element is a 3 elements list with named elements 1) "x" a vector of increasing x locations (at which the covariate is sampled) 2) "y" a vector of increasing y locations (at which the covariate is sampled) 3) "z" a size(x)*size(y) matrix giving covariate values at location (x, y)

Value
