    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。 n+Fl|4  
    3o"~_l$z  
    配置:在执行调用之前,我们需要在Matlab命令行窗口输入如下命令: 5x=tOR/h  
    enableservice('AutomationServer', true) ZiVTc/b  
        enableservice('AutomationServer') {^MR^4&}(  
    pZjyzH{~  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 M#F;eK2pf  
    ;<ed1%Le,  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: -2% [ ]  
    1. 在FRED脚本编辑界面找到参考. B0Xn9Tvk  
    2. 找到Matlab Automation Server Type Library ro^Y$;G  
        3. 将名字改为MLAPP 5-=mtvA:

    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。 ]9;WM.

    1. 创建Matlab服务器。 7CrWsQl u  
    2. 移动探测面对于前一聚焦面的位置。 Q8z>0ci3o  
    3. 在探测面追迹光线 i&"I/!3Q@  
    4. 在探测面计算照度 /PHktSG  
    5. 使用PutWorkspaceData发送照度数据到Matlab (Ozb+W?  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 |W\CV0L2  
    7. 用Matlab画出照度数据 s {$c8  
    8. 在Matlab计算照度平均值 4i/TEHQ  
    9. 返回数据到FRED中 8h;1(S)*Z
