Matlab ignores it, same as with a nan. This needs a bit of thought and checking. Mike went to some trouble, I believe, to make nans work without running everything through masked arrays--whether this is actually *faster* than doing an initial masking operation when needed and then using masked arrays everywhere internally when bad values are present, I don't know. It is possible that everything could be made to work with infs simply by changing all "isnan(x)" to "~isfinite(x)", which has the advantage of being slightly faster (surprisingly) as well as more general.
