I just noticed that saving/overwriting into existing file is much slower
that creating a new one:
octave:1> xxx = repmat (ones(2000), [1,1,4,10]); octave:2> tic; save xxx1.oct xxx -binary; toc Elapsed time is 0.835598 seconds. octave:3> tic; save xxx1.oct xxx -binary; toc Elapsed time is 3.52093 seconds. octave:4> tic; save xxx1.oct xxx -binary; toc Elapsed time is 3.47683 seconds.
