As often the case in matlab, the most efficient solution is to avoid loops. The simplest way to solve your problem is to convert your latitude and longitude into matrix coordinates (by rounding down the numbers, subtracting the min of each column, and adding 1) and use...
Sum the Elements of a Matrix Using thesum()Function in MATLAB To find the sum of all the elements of a matrix, we can use thesum()function. In the case of a matrix, we have to use thesum()function two times, one for rows and one for columns, but in the case of a vector, we...
