simulink仿真自适应干扰抵消模型时报错！！！求帮助！

[jiaming]

3023本人最近在学习自适应干扰抵消，参照《离散信号处理——应用与实践》第2版P295~297，用simulink搭建模型仿真时会报错Error in embedded hardware settings on Hardware Implementation pane of Configuration Parameters dialog box: word length for "short" is longer than that for "int". Word length for "short" is 32, while that for "int" is 16.
这是为什么？在matlabR2007a以上的版本都会出现这个错误！求大侠帮忙！！
