ssIsSampleHit(S,st_index,

tid)

Used in mdlOutputs or mdlUpdate when your S-function has

multiple sample t imes to determine what task your S-function

is executing in. This should not be used in single rate

S-functions or for the

st_index corresponding to a continuous

task.

ssIsContinuousTask(S,tid)

Used in mdlOutputs or mdlUpdate when your S-function has

multiple sample times to determine if your S-function is

executing in the continuous task. This should not be used in

single rate S-functions, or if you d id not register a continuous

sample time.
