    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。 ?;ukvD  
    %Q"(/jm?  
    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: cD}Sf>  
    enableservice('AutomationServer', true) } (FPV*mS  
    enableservice('AutomationServer') k-LEI}h  
    )q~DTR^z-  
    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 Kyg=$^{>G

    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: u_O# @eOc  
    1. 在FRED脚本编辑界面找到参考. ,?cH"@ RJ  
    2. 找到Matlab Automation Server Type Library }%!tT\8  
    3. 将名字改为MLAPP J1ON,&[J  
    c@(&[/q!  
    K!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。 @I3eK^#|P

    现在将脚本代码公布如下,此脚本执行如下几个步骤: CON0E~"  
    1. 创建Matlab服务器。 1`bl&}6l|E  
    2. 移动探测面对于前一聚焦面的位置。 <X7\z  
    3. 在探测面追迹光线 A#h/B+  
    4. 在探测面计算照度 9]'&RyH=#  
    5. 使用PutWorkspaceData发送照度数据到Matlab R*pC.QiB~  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ]B\H ~Kn  
    7. 用Matlab画出照度数据 = duks\)O  
    8. 在Matlab计算照度平均值 T? ,P*l  
    9. 返回数据到FRED中 zDOKShG
