Hello, I am trying to split a vector into more pieces using a for loop. I have a vector, Lat, which contains latitude points. I wish to add more points in a linear fashion between the existing points in my Lat vector.

In order to do this, I am trying to use a for loop and the linspace operator as follows, splitting each interval in five new pieces.

 for i = 1:length(Lat)-1
    latitude(i) = linspace(Lat(i),Lat(i+1),5);
end

This does not work. How do I make the for loop understand that I wish to obtain a new vector containing all the points created using the linspace operator?

Try this:

for i = 1:length(Lat)-1
    latitude(i,:) = linspace(Lat(i),Lat(i+1),5);
end
latitude = reshape(latitude', 1, []);
