I have a matrix with a list of latitude and longitude coordinates (64,800×3). Each latitude and longitude pair have their own index number.
[Index Lat Lon;10521 -45.5 50.5;10522 -45.5 51.5;10523 -45.5 52.5]
I have another matrix with a list of latitude and longitude numbers, but no index numbers. Also, this matrix is not the same size as the previous matrix. (250×2; It has Lat and Lon only, no index number yet.)
I want to write a script that will examine the pairs of latitude and longitude coordinates for each matrix. When there is a pair that matches between the matrices, it would assign the same index number to the second matrix from the first matrix.
