Hello:
I have polygon shape file, where the shape file comprises of multiple polygon each in a struct format. I want to superimpose gridded data over it, however, I want to mask the data points which are not located within these polygons. I came across several example, for example, one here: https://de.mathworks.com/matlabcentral/answers/311766-how-to-mask-data-points-outside-a-border-using-geoshow
Since ours is not a standard shapefile as available within MATLAB but an area of watershed comprising several polygons, the code shown here is not working for me. Could any one pls. suggest how to remove the data points from visualization which is not located within the polygon.

REad about inpolygon, this will give you indices of points lying inside the polygon.
