    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。 |4pl}:g/Z  
    z\UXn RL  
    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: BH~zeJ*Pr  
    enableservice('AutomationServer', true) 6S n&; ap  
    enableservice('AutomationServer') Ag+B*   
    "\}h  
    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 9Xa.%vw>

    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: xYv;l\20.  
    1. 在FRED脚本编辑界面找到参考. 2 yANf  
    2. 找到Matlab Automation Server Type Library Xp06sl7 M  
    3. 将名字改为MLAPP P/[RH e  
    XgnNYy6W  
    4OJD_  
    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。 %B#T"=Cx

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Uvc$&j^k  
    1. 创建Matlab服务器。 g| 3bM  
    2. 移动探测面对于前一聚焦面的位置。  *BM#fe  
    3. 在探测面追迹光线 `<v$+mG  
    4. 在探测面计算照度 4\|Q;@f  
    5. 使用PutWorkspaceData发送照度数据到Matlab U*yOe*>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 .s4v*bng  
    7. 用Matlab画出照度数据 L?|}!  
    8. 在Matlab计算照度平均值 JM/\n 4ea:  
    9. 返回数据到FRED中 B?^~1Ua9Zv
