Hi All,
I have two matrices for latitude and longitude with the following size: Latitude (41x 1) and Longitude(81 x 1)
I need to get an output matrix of the size ((41 * 81) x 1) or ((41*81) x 2) - size is containing pairs of coordinates, so basiically first row of Latitude paired with all longitudes (one at a time), then take second row of Latitude and apply the same. (How I imagine it is done)
I would appreciate any guidance on how to perform this task.
Cheers,
NZ

I would not think you need to create such a matrix. That matrix simply duplicates lots of data. The truly useful and unique data are still your original data, the 41 Latitude and 81 Longitude data.
What you need is the index of your location, then you can find out the position of your location. For example
x=4;
y=5;
YourLocation=[Latitude(4), Longitude(5)]
