cacheFunc

Works with VSimBase, VSimEM, VSimPD, VSimPA, and VSimMD licenses.

Defines a function that remembers its last arguments and value, and avoids recalculation if possible.

cacheFunc Parameters

STFunc (block, required): The function to be cached.

timeIsIrrelevant (bool): Whether the change is time is relevant to the function.

irrelevantDirs (integer vector): Any direction where the change is irrelevant to the function.

Example cacheFunc Block

<STFunc memDrive>
  kind = cacheFunc
  irrelevantDirs = [1 2]
  <STFunc drive>
    kind = expression
    expression =  amp*H(T_DRIVE-t)*cos(K*x)*sin(OMEGA*t)
  </STFunc>
</STFunc>
