% bounds on the design variables, X, so that a solution is found in % the range LB <= X <= UB. Use empty matrices for LB and UB % if no bounds exist. Set LB(i) = -Inf if X(i) is unbounded below; % set UB(i) = Inf if X(i) is unbounded above. ...
应该使用VariableStepDiscrete仿真模式,而不是ode45模式。有两种更改方法:1、在该model的工具栏上选择simulation,再选择并进入configuration parameters界面,从solver里面设置,type设置为variable-step,solver设置为discrete;2、或者在Diagnostics子菜单里将'Automatic solver parameter selection' 设置为none。
