using inpolygon inside a for loop, GPU memory usage increase at each loop iteration although variables have always same dimensions.
for ii =1:Nloop
% do something to retrieve AntennaLatVertex, AntennaLonVertex
TF = inpolygon(Lat, Lon, AntennaLatVertex, AntennaLonVertex);
end
AntennaLatVertex and AntennaLonVertex are 4x1 matrix representing "rectangle" vertex. all variables are gpuArray at each loop iteration memory increase by significant amount (both on linux and Windows platform) any ideas ?
