It can be shown by looking at sk = [0,-1.0,1.0] print 250.0*sk[:,newaxis] This should give something useful (not zeros). The problem was a seemingly harmless change in _IsContiguous that allowed for 0-strided arrays to be called contiguous. This caused havoc with the multiplication function later which relied on an accurate _IsContiguous function. This change was in r2765 (I suspect you checked out a change with that in it). The change could cause problems where-ever you use newaxis with scalar multiplication. The problem should be fixed in SVN. Very sorry... -Travis Using Tomcat but need to do more?
