The code included herein enables the assembly of linearised state-space systems based on the previous solution of a nonlinear problem that will be used as linearisation reference.
The code is structured in the following way:
Assembler: different state-spaces to assemble, from only structural/aerodynamic to fully coupled aeroelastic
Src: source code required for the linearisation and utilities for the manipulation of state-space elements
