This program gives me the numer of NaNs in all the world but not in one particular country.
worldmap('Spain')
load coastlines
sum(sum(isnan(coastlat)))

You may use shaperead function to get latitudes and longitudes of a particular country. You can refer to the following example to count the numbers of NaNs in a particular country coordinates
Val = shaperead('landareas', 'UseGeoCoords', true,...
'Selector',{@(name) strcmp(name,'Africa and Eurasia'), 'Name'});
sum(isnan(Val.Lat));
