MATLAB: Mask the data relating to the contour of the continents

mask continents

Does anyone have a solution to mask the data relating to the contour of the continents of a netcdf file?

Perhaps inpolygon will do it?

netcdf.putAtt(ncid1,3,'_FillValue', cast(-999, class(pr)) );

Take a look at the start, count, and stride inputs that are associated with most netcdf methods, including getVar. For example,

mydata = netcdf.getVar(Ncid111, varid, [220 114 1], [1 1 Inf], [1 1 24]);

What version of Matlab are you running? If it's relatively recent, you can simplify things by using ncread:

mydata = ncread('file.nc', varname, [220 114 1], [1 1 Inf], [1 1 24]);
