MATLAB: How to save no variable

errorjsonno variablesave

This is my code.
Lat = 30;
Lon = 12;
base_url =[ 'http://maps.googleapis.com/maps/api/geocode/json'];
formatSpec = '%4.6f';
LatLon = [num2str(Lat,formatSpec),',',num2str(Lon,formatSpec)];
request_url = [base_url '?latlng=' LatLon '&sensor=true_or_false']
docNode = urlread(request_url);
data = json.load(docNode);
n = size(data.results,2);
i = 1;
for i = 1:n
a = data.results(1,i).types(1,1);
b = data.results(1,i).formatted_address;
if strcmp(a,'country') == 1
sprintf(b)
else if strcmp(a,'locality') == 1
c = b;
sprintf(c)
end
end
end
save('name.mat','b','c')
name = load('name.mat','-mat');
N = struct2cell(name);
When you run the above code , the following message will appear. Variable 'c' not found.
So, I want to save as " no data " when there is no value of c or b as the message. What should I do?

  • In your test assign something to your variable c
    if strcmp(a,'country')
    sprintf(b)
    c='no data'
    elseif strcmp(a,'locality')
    c = b;
    sprintf(c)
    end
