My eyes are deceiving me. I came across a slow loop and to my surprise traced it to the min function. But I'm wondering how this can be because I looked through the source code and the min/max commands inside minmax.cc and dNDArray.cc look identical except obviously for the change in sign when testing order. I have a fairly recent version of 2.1.64.

I put together a little test script. Someone please try the attached script. My result is

octave:1> minmaxtime
looptime = 0.044205
maxtime = 0.081752
mintime = 7.5832

Thank you,


octave:1> minmaxtime
looptime = 0.035128
maxtime = 0.065962
mintime = 0.30040



p.s. 2.1.64 + octave-forge-2004.11.16 / athlonMP 2000 MHz
