Your code won't evaluate because we don't know what perpframe is. Is it some kind of police procedure? David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: T Harris [mailto:tdh1967 at bellsouth.net] To: mathgroup at smc.vnet.net I am taking linear algebra and I have questions about the following code. Can someone run it and help me here? These are the two questions --> (1) How do I measure the planar area of this flat thing? (2) What plane does this ellipsoid plot out on? What would I do in any case like this in the future to determine the plane? Thanks for any help you can give.
