fitting using fitnlm with bounded parameters

I would like to estimate the amplitude and phase of a set of noisy data that should follow the model A sin(wt+phase) .
I can do this with NonLinearModel.fit, but it's not obvious how I can provide bounds on my parameters (phase should be between 0 and 2pi and the amplitude should be positive).
I have read that these nonlinear fitting functions cannot apply constraints to the model. Is this true that there's no way to use these nonlinear fitting methods with bounds on the parameters?
