FRED如何调用Matlab

简介:FRED作为COM组件可以实现与Excel、VB、Matlab等调用来完成庞大的计算任务或画图,本文的目的是通过运行一个案例来实现与Matlab的相互调用,在此我们需要借助脚本来完成,此脚本为视为通用型脚本。 l AF/O5b  
P|mV((/m4  
配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 1T(:bM_t`7  
enableservice('AutomationServer', true) :2#8\7IU^'  
enableservice('AutomationServer') xlQl1lOX  
/">A3bq  
结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信。 n{oRmw-  
TG ,T>'   
在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: V\k?$}  
1. 在FRED脚本编辑界面找到参考. {=]1]IWt  
2. 找到Matlab Automation Server Type Library Z]-C,8MM  
3. 将名字改为MLAPP (ATvH_Z

在Matlab里面有两种常用的数据发送选项PutWorkspaceData 及PutFullMatrix,PutWorkspaceData适用于存储一般的数据在工作区,并赋予其为变量,PutFullMatrix试用于复数数据。 lLD-QO}/

1. 创建Matlab服务器。 E]x)Qr2Ju  
2. 移动探测面对于前一聚焦面的位置。 56!>}!8!  
3. 在探测面追迹光线 .eQIU$Kw!O  
4. 在探测面计算照度 YDEUiZ~  
5. 使用PutWorkspaceData发送照度数据到Matlab jn+NX)9  
6. 使用PutFullMatrix发送标量场数据到Matlab中 slSQ\;CDA  
7. 用Matlab画出照度数据 FQNw89g  
8. 在Matlab计算照度平均值 wm@ />X  
9. 返回数据到FRED中 b?&=gm%oU
