Distance between GPS points

Calculates distance between two GPS coordinates through Carlson model.

This program calculates distance between two decimal GPS coordinates matrices. The model used in this calculation utilizes Carlson (1999) model.

Example:
Import the sample_data.xls file, creating vectors from each column using column names or you can enter your own GPS data into lat1,long1,lat2 and long2 variables, then run this m-file.

The output of this program is
1- Calculated distance between Point1(long1(i),lat1(i)) and point2(long2(i),lat2(i)) shwon as distance_m (metric system) and distance_ft (US system)
2- Plot of long1 vs lat1
3- Plot of long2 vs. lat2
4- Plot of distance_m vs. # points
