SampleClock
This block generates a periodic activation signal. Periodic activation signals are special because they are made up of events that occur at regular intervals of time. Note that an activation signal made of up of events at regular intervals of time is not necessarily a periodic activation signal. For example the activation signal produced by the EventClock is not periodic. All periodic activation signals under the same SyncTag are considered synchronous.

Description
The SampleClock block generates a periodic activation signal. Periodic activation signals are special because they are made up of events that occur at regular intervals of time. Note that an activation signal made of up of events at regular intervals of time is not necessarily a periodic activation signal. For example the activation signal produced by the EventClock is not periodic. All periodic activation signals under the same SyncTag are considered synchronous.
When period is 0, blocks connected to the clock are always active.
When period is -1, blocks connected to the clock are activated at initial time.
When period or offset are given as a vector [x;y;z], they are evaluated as (x/y)*10^(z).
