How to interpolate NaN in a 3d grid?

Hi all,

I have a 3D grid with lon, lat and time (size= 40x144x720) with some NaN. I need to interpolate using a linear method this NaN values.

I have tries with interp1gap and some loops, but I have some errors with that function.:

n=720
for i=1:40
    for j=1:144
        for k=1:n
            mod_atl_filtrado(i,j,k)=interp1gap(mod_atl(i,j,k)');
        end
    end
end

Do you know how to do this?

Thank you very much
