Right, but that method involves looping over each i. Is there a way to do this without loops? |

This computes the minimum element in each row of A, it's not quite what I was looking for. |

I can see no difference in speed (nan vs. inf), but Matt's solution is incomplete as I understand the problem. |

It's not the first time I observe much slower operation on NaN, and I did very careful timing in various development of codes. I know that by default Matlab NaN is a "quiet" NaN (as opposed) to signaled. So in principle it does not trigger any floating point handler. So I don't have any explanation. |
