inpolygon

in = inpolygon(x, y, polygon)

or

in = inpolygon(point, polygon)

Returns in indicating if the query points specified by x and y are inside of the polygon area defined by: - polygon: a GMTdatset defining the polygon or a Mx2 matrix of reals that should have the first and last elements equal.

• point: a Mx2 matrix or a two elements vector with the x and y point coordinates. Depending on the number of query points in point, we return either an Int or a Vector{Int}.

Returns:

• in = 1
• on = 0
• out = -1
