Warning: The model 'moxing' does not have continuous states, hence using the solver 'VariableStepDiscrete' instead of solver 'ode45'. You can disable this diagnostic by explicitly specifying a discrete solver in the solver tab of the Configuration Parameters dialog, or setting 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics tab of the Configuration Parameters dialog.
Warning: Output port 1 of 'moxing/Complex to Magnitude-Angle' is not connected.
Warning: Block diagram 'moxing' contains 1 algebraic loop(s). To see more details about the loops use the command line Simulink debugger by typing "sldebug moxing" in the MATLAB command window. To eliminate this message, set the Algebraic loop option in the Diagnostics page of the Simulation Parameters Dialog to "None".
Found algebraic loop containing:
  'moxing/Divide'
  'moxing/Derivative2'
  'moxing/Abs1' (discontinuity)
  'moxing/Product4' (algebraic variable)
  'moxing/ '
  'moxing/Product2'
  'moxing/Ad1'
  'moxing/1//C1'
  'moxing/Sum3'
  'moxing/1//Ad1'
  'moxing/Derivative1'
  'moxing/Derivative'
  'moxing/md'
  'moxing/Abs' (discontinuity)
  'moxing/Switch' (discontinuity)
  'moxing/Product' (algebraic variable)
  'moxing/Sum' (algebraic variable)
  'moxing/1//Ad'
  'moxing/1//C2'
  'moxing/Ad'
  'moxing/Sum1' (algebraic variable)
  'moxing/Derivative3'
  'moxing/Product1'
  'moxing/Sum2' (algebraic variable)
Warning: Discontinuities detected within algebraic loop(s), may have trouble solving.
Warning: Using a default value of 0.2 for maximum step size.  The simulation step size will be equal to or less than this value.  You can disable this diagnostic by setting 'Automatic solver parameter selection' diagnostic to 'none' in the Diagnostics page of the configuration parameters dialog.
Warning: Convergence problem when solving algebraic loop containing 'moxing/Divide' at time 2.842170943040401e-015.  Simulink will try to solve this loop using Simulink 3 (R11) strategy. Use feature('ModeIterationsInAlgLoops',0) to disable the strategy introduced in Simulink 4 (R12).
谁晓得是什么问题啊，请告诉我，谢谢
