Signed distance from points p to boundary of rectangle to allow easy definition of regions in distmesh2d.
p
distmesh2d
mesh.drectangle(p, x1 = -1/2, y1 = -1/2, x2 = 1/2, y2 = 1/2, ...)
a vector of length nrow(p) containing the signed distances
nrow(p)
A matrix with 2 columns, each row representing a point in the plane.
