Select an IDLTI model with at least one input and an IDDATA object with matching number of inputs and, for discrete time systems, equal sample times. For discrete models, the input may alternatively be specified as a real matrix where the number of columns matches the number of model inputs. The selection order does not matter for determining the enabled state of the plot action.
