T-MATS: Model Source Library Block
The Iterative Newton Raphson Solver with Jacobian Calculator block will supply the inputs to iteratively drive the outputs of a system to zero.

This will be performed in three steps.
1) Jabobian calculator sends Perturbations to the plant then calculates the plant Jacboian based on the system response.
2) The Newton Raphson will use the inverse of the Jacobian to iteratively step the system toward solution.
3) Once the solution has satisfied the conditions the Newton Raphson is shut off.

This module is designed for dynamic systems and should be paired with a "do... while" block in Simulink. The "do...while" block and this module should both be located in the same subsystem as the plant that is to be solved for.
