    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。 YDE;mIW  
    NRe{0U}nO  
    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: paF$ o6\  
    enableservice('AutomationServer', true) ak 94"<p  
    enableservice('AutomationServer') `rzgC \  
    Nih8(pbe  
    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 M<hX !B  
    \R#]}g0!  
    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:  w~wpm7  
    1. 在FRED脚本编辑界面找到参考. {s&6C-  
    2. 找到Matlab Automation Server Type Library ]|ew!N$ar=  
    3. 将名字改为MLAPP uO8z.

    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。 H3"90^|,@

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Hg(%g T  
    1. 创建Matlab服务器。 \yP\@cpY{  
    2. 移动探测面对于前一聚焦面的位置。 M}2a/}4   
    3. 在探测面追迹光线 MwMv[];I  
    4. 在探测面计算照度 |giV<Sj  
    5. 使用PutWorkspaceData发送照度数据到Matlab f-6-!  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 [+<lm 5t  
    7. 用Matlab画出照度数据 *Y8nea^$  
    8. 在Matlab计算照度平均值 {WfZE&B  
    9. 返回数据到FRED中 >|Ps23J#
