Hello I'm testing the best way to do a grid like, I tried the 2 following methods:
tic() k1 = repmat(kx,1,nx) k1v = vec(k1)' k1m = repmat(k1v,nb,1) toc() # 0.0256 tic() ka = repeat(kx,outer=[nx,nb])' toc() # 0.477 I dont understand why the second way with the "one line repeat" is 20 times slower than the repeat/vec/repeat ? thanks in advance best Antony
