			% BILINEAR_MEX compute a bilinear interpolation of an image at the provided
			% (sub)pixel coordinates.
			%
			% PIXS = BILINEAR_MEX(IMG, XCOORD, YCOORD) returns the bilinear interpolation of the
			% pixel values PIXS from IMG at the provided coordinates (XCOORD, YCOORD) tuples.
			% PIXS has the same dimensions as XCOORD. Note that coordinates should be provided
			% as carthesian coordinates, not as matrix indexes !
			%
			% PIXS = BILINEAR_MEX(IMG, COORDS) where COORDS is a Nx2 matrix with each row
			% corresponding to a [X_coord, X_coord] tuple.
			%
			% PIXS = BILINEAR_MEX(..., BOUNDARY) defines in addition the type of boundary
			% conditions to be used. Available behaviors are: 0 (NaN outside), 1 (circular),
			% 2 (replicate), 3 (symmteric). See imfilter for more details on such behaviors.
			% If BOUNDARY has two elements, X and Y behaviors can be defined separately.
			% By default, both coordinates are set to 0.
