Hey Sasha. Your defnition may be more correct, but I have to confess I don't understand it. "Universal function. Universal functions follow similar rules for broadcasting, coercion and "element-wise operation"." What is "coercion"? (Who or what is being coerced to do what?) and what does it mean to "follow similar rules for ... coercion"? Similar to what? --bill ------------------------------------------------------------------------- Using Tomcat but need to do more? Need to support web services, security?
