Find elements from a matrix and sum variables from other matrix
1 vue (au cours des 30 derniers jours)
I have a matrix of lat long (406, 964) say A, and B. I also have a huge matrix of length 36000 and 3 variables (lat, long, intensity), say C. The lat lon in C have repeated values. I need to find only the elements of A and B that match in C, but also sum the intensity values of all those matching coordinates.
Thank you. Look forward to you help.
