WSMInputFunctions is being phased out in favor of the association key "Inputs" in functions introduced experimentally in Version 11.3.


is an option for WSMSimulate and WSMSimulateSensitivity that specifies values for input variables.

Details and Options

  • WSMInputFunctions takes the following values:
  • {var1fun1,}use funi[t] as input for vari at time t
    {var1{f1,f2,},}run simulations in parallel, with fj[t] as input for vari
  • Input functions can be set for all variables in WSMModelData[mmodel,"InputVariables"].
  • Each vari can be either a string or DotName.
