how to write a code to extract a positive latitude value for the corresponding positive longitudinal cell value

2 次查看(过去 30 天)
suppose we have longitudinal =[-50;-60;-70;-80;-90;-100;-50.5;-60.5;-70.5;-80.5;-90.5;-100.5;50;60;70;80;90;100;50;60;70;80;90;-100.5]
and latitude =[-5;-10;-20;-30;-40;50;-1.5;-10.5;-20.5;-30.5;-40.5;50.5;0;10;20;30;40;50;0.5;10.5;20.5;30.5;40.5;50.5] data point like this then for the longitudinal range(i.e 50 to 100) we should get the postive latitude range(i.e 0 to 40)
for example :the longitudinal value 90 have the corresponding latitudinal value 40 and similarly longitude value 100 have latitude 50.
plz help in getting the code and the range should be for longitudinal(50 to 100) latitude (0 to 40) ,within this range only i have to get data points

% filter
idx = longitudinal >= 50 & longitudinal <= 100 & latitude >= 0 & latitude <= 40;
% selection
longitudinal2 = longitudinal(idx);
latitude2 = latitude(idx);

yes
suppose latitude is column 1 and longitude is column 2 so i wanted to extract the longitudinal value and their corresponding latitude value so that my output should come like this:
latitude longitude
0 50
10 60
30 80
40 90
50 100
0.5 50.5
10.5 60.5
20.50 70.5
40.5 90.5
and this output i wanted to store in another variable

Sorry but I still don't understand: isn't this the output you get running my code and concatenating the two outputs like this:
out = [latitude2 longitudinal2];
?
