Many of the following demonstrations are included in various Connexions modules. We provide this collection for your convenience. The demonstrations have all been created using LabVIEW, but one only needs the Run-Time Engine and a small helper application to use them. Please see this document for instructions on how to use these demonstrations. Change of Basis The following demonstration allows you to explore changing the basis used to represent a vector. See here for instructions on how to use the demo. Complex Numbers The following demonstration allows you to explore the complex plane and look at the different ways of representing complex numbers.
