Hello, I am just getting started using matlab and am having trouble with generating contours. Basically I have the latitude and longitude of multiple points in separate vectors, (1 by n), then also have a vector containing data values that correspond to each of these locations (also 1 x n). I have a map of the location using geoshow, but would like to create contours based on the data associated with each location. I have tried a couple of the mapping contour functions, but nothing seems to take what I have as inputs. Any help on this would be great! Thanks!
