hello, I am trying to calculate the results of a function between two matrices:
>>> F.shape (170, 2) >>> T.shape (170, 481, 2) Where F contains lat/lon pairs and T contains 481 lat/lon pairs for 170 trajectories of length 481 I want a new array of shape (170,481) containing the results of my distance function: gcd(x1,y1,x2,y3): """ returns great circle distance""" ... return dist Is there a way to do this without the use of loops? I'm thinking something along the lines of: distances = [[gcd(f[0],f[1],t[0],t[1]]) for f in F] for t in T] But obviously this doesn't work...
