| function u = models.muscle.examples.LongForceBC.getInputs | ( | ) |
Returns the inputs \(u(t)\) of the model.
if neumann boundary conditions are used, this input is multiplied with the mu(3) parameter, which determines the maximum force that is applied. u(t) determines its temporal strength.
this.Model can be used to get access to the model this configuration is applied to.
| u | The cell array of input functions to use within this model. |
