进行simulink仿真是出现的这种error是什么错误

huishuimm

<P>在仿真时间为1秒的时候都没有这个错误的，当仿真时间改为2秒后，系统运行到1.3秒左右（每次错误时间不确定）就提示错误，运行也就停下来了<BR><BR>请问一下，这是什么错误？怎样避免？<BR><BR>谢谢</P>

我的没有死机，内存是1g的，就是提示了错误之后停下来了<BR>错误提示图片怎么贴上来啊，我不会哦<BR>直接打上来吧(一共提示了两个错误，除了Summary不一样，其他均一样)，请高人指点<BR>Message:Model error<BR>Source:Unknown<BR>Summary:1.Memory allocation error<BR>        2.Error converting logging variable to MATLAB format.(后面还有很多乱码)

<H3>Solution:</H3>
<P>Memory allocation errors are due to your Operating System not having the resources to allocate any more memory for the simulation.<BR><BR>Below are a couple of things that you can do to avoid the memory allocation errors in Simulink:<BR><BR>1) Turn off the Workspace I/O (to do that, in the Simulink model go to Simulation=&gt;Parameters=&gt; Workspace I/O and uncheck the time and output boxes).<BR><BR>2) Increase the step size of the simulation<BR><BR>3) Reduce the length of the simulation <BR><BR>4) Increase the virtual memory of your computer (right click on the My Computer Icon, go to Properties and choose Performance).<BR><BR>5) 32M of RAM may not be enough memory for running long simulations on Simulink models. You might consider increasing your RAM memory.<BR><BR><BR>For other options on improving simulation performances you can go to page 4-27 of the Using Simulink manual, if you do not have the manual you can use the on line version at:<BR><BR><a href="http://www.mathworks.com/access/helpdesk/help/toolbox/simulink/ug/f11-33464.html" target="_blank" >http://www.mathworks.com/access/helpdesk/help/toolbox/simulink/ug/f11-33464.html</A> </P></DIV></TD></TR></TABLE></P>

多谢你的回答，但是我在Simulation=&gt;Parameters里面，没有找到 Workspace I/O这一项啊，是不是跟版本还有关？<BR>我用的是MATLAB7.1

遇到过，是在７．几秒出现，我一般不搞那么长时间，呵呵．ＬＺ的机子不错啊，１Ｇ的内存

谢谢

我的模型里面就是
示波器太多，然后都没有限制数据多少
然后仿真时间稍长
看了这个帖子
豁然开朗
