Hello,
I have a matrix of 419x419 data that has NaN's throughout. I have a longitude vector of 419x1 and a latitude vector of 419x1. I would like to convert the data (419x419) into three columns: latitude, longitude, and correlated data. Is there a way to do this?
Thanks,
Melissa

[tLat, tLong] = ndgrid(Latvec, Longvec);
LLdata = [tLat(:), tLong(:), dataarray(:)];
Note: you did not specify whether the 419 x 419 has latitude running down the columns or across the rows. You will want to test the above with a subset of your data before you generate the whole thing.
