This symbol represents the output of a dynamical system.
This symbol represents the (possibly multi-dimensional) output of a dynamical system, given by the output function \( \htmlClass{sdt-0000000056}{O} \).
The symbol \( \mathbf{y} \) represents an output of a dynamical system at some time point. This corresponds to an observation or measurement, which can take different forms depending on the formulation of the output function \( \htmlClass{sdt-0000000056}{O} \).
