Gradient of raster using bilinear interpolation
Description
Gradient of raster using bilinear interpolation
Usage
grad_raster(rast, pts)
Arguments
rast
Raster object
pts
Matrix with two columns (one for each coordinate)
Details
The gradient has a closed form solution if bilinear interpolation
is used, as described in Appendix C of Michelot (2019, PhD thesis).

Value
Matrix with same dimensions as pts, where the first column
gives the gradient along the first dimension, and the second column
along the second dimension.
