JumpStateSpace
This block implements a continuous-time linear state-space system with the possibility of jumps in the state. The first input is the regular input signal of the linear system, the second carries the new value of the state which is copied into the state when an event activates the block through its unique activation input port.

Description
The JumpStateSpace block realizes a continuous-time, linear state-space system with the possibility of jumps in the state. The block has two inputs: The first input is the regular input of the linear system; the second carries the new value of the state which is copied into the state when an event arrives at the block's unique input port, meaning that the state of the system jumps to the value present on the second input (of size equal to that of the state). The system is defined by the (A,B,C,D) matrices and the initial state x0. The dimensions must be compatible. The sizes of inputs and outputs are adjusted automatically.
