If you have all the lat and lon values, then just put each into kmeans separately:

 

numColumns = 26; % Or however many columns you know there to be.
[xIndexes, xCentroids] = kmeans(lon, numColumns);
numRows = 50; % Or however many rows you know there to be.
[yIndexes, yCentroids] = kmeans(lat, numRows);
The values of the columns (x or longitude values) will be in xCentroids.
 
The values of the rows (y or lat values) will be in yCentroids.
