Improve performance in reflectometry engine
|Status:||Backlog||Start date:||30 Apr 2019|
Currently it uses backwards computation of reflection/transmission coefficients and the bisection to find the last layer with non-zero transmission.
My previous attempt to compute coefficients directly (from top to bottom) failed because of scheme instability.
Still getting rid of at least bisection would change the worst-case complexity of computation from N * log(N) to N, where N is the number of layers.
