就是把已经建立好的网络,用SIMULINK仿真。回出现The model 'untitled' 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: Using a default value of 0.2 for maximum step size. The simulation step size will be limited to be 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.
不知道是什么意思。。
