Methods for the interpolation of DLTI ROMs¶
This is library for state-space models interpolation. These routines are intended for small size state-space models (ROMs), hence some methods may not be optimised to exploit sparsity structures. For generality purposes, all methods require in input interpolatory weights.
The module includes the methods:
transfer_function(): returns an interpolatory state-space model based on the transfer function method . This method is general and is, effectively, a wrapper of the
BT_transfer_function(): evolution of transfer function methods. The growth of the interpolated system size is avoided through balancing.
