MATLAB: Cellfun couple inpolygon

cellfuninpolygon

Hi all,
I have a cell denoting 4 grid blocks like this:
parameter{:}
ans =
    1.5000    1.5000
    1.7500    1.5000
    1.7500    1.7500
    1.5000    1.7500
ans =
    1.5000    1.7500
    1.7500    1.7500
    1.7500    2.0000
    1.5000    2.0000
ans =
    1.7500    1.5000
    2.0000    1.5000
    2.0000    1.7500
    1.7500    1.7500
ans =
    1.7500    1.7500
    2.0000    1.7500
    2.0000    2.0000
    1.7500    2.0000
My question is, if now I have a x-y coordinate, say x = 1.63, y = 1.05, how can I loop through these 4 cells to determine whether x-y is in polygon or not? I think this can be solved by apply inpolygon using cellfun for all cell elements, but I'm not too sure about how to do it.
Many thanks!

query_x = 1.63;
query_y = 1.05;
does_it_match = cellfun(@(poly) inpolygon(query_x, query_y, poly(:,1), poly(:,2)), parameter)
