Sample Time

Control block execution rates; assign discrete, continuous, or hybrid sample time

The sample time of a block is a parameter that indicates when, during simulation, the block produces outputs and if appropriate, updates its internal state. The internal state includes but is not limited to continuous and discrete states that are logged. In engineering, sample time refers to the rate at which a discrete system samples its inputs. Simulink^® allows you to model single-rate and multirate discrete systems and hybrid continuous-discrete systems through the appropriate setting of block sample times that control the rate of block execution (calculations).
