I have a grid of points with coordinates and I need to select only points on the land.
I can load coastlines, then split contours with NaN inside (2 of them) into separated ones, then convert each contour to alphaShape, and then apply inShape to each point and alphaShape, but maybe there is simpler way?
Thanks

Do you have the mapping toolbox? Use https://www.mathworks.com/matlabcentral/fileexchange/48661-landmask If so it is as simple as:
landmask(lat,lon);
