Gamma-Re (γ-Re) transition model is a two equation model used in Computational Fluid Dynamics (CFD) to modify turbulent transport equations to simulate laminar, laminar-to-turbulent and turbulence states in a fluid flow. The Gamma-Re model does not intend to model the physics of the problem but attempts to fit a wide range of experiments and transition methods into its formulation. The transition model calculated an intermittency factor that creates (or extinguishes) turbulence by slowly introducing turbulent production at the laminar-to-turbulent transition location. (Wikipedia).
In this video, I show that if you have two coordinate systems, it's actually very easy to go from one to the other (and back), just use a change of coordinates matrix! More specifically, I derive the formula for the change of coordinates matrix and give you a nice example. This is a handy

Change of Basis Between Two Nonstandard Bases (Example)
This video explains how to find a transition matrix between two nonstandard bases and how to find the coordinates of a vector.

Suppose you have two bases of the same space and the matrix of a linear transformation with respect to one bases. In this video, I show how to find the matrix of the same transformation with respect to the other basis, without ever having to figure out what the linear transformation does!
