Is matlab function distance is broken ?
7 views (last 30 days)
I try to calculate the distance between two points on a sphere. It seems that the function distance is built-in https://www.mathworks.com/help/map/ref/distance.html
But I'm unable to make it work, even the examples in the doc seem to not work :
arclen = distance('gc',[37,-76],[37,-9])
arclen = distance('rh',[37,-76],[37,-9])
I always have this error :
Check for missing argument or incorrect argument data type in call to function 'distance'.
I even tried syntax like that :
[arclen,az] = distance('gc',[37,-76],[37,-9])
But nothing seems to work, why ? I'm using Matlab R2020a, is it deprecated ?
