    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_'*&8  
    A(;J  
    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: Z''Fz(qMC  
    enableservice('AutomationServer', true) Ob0=ZW`+&  
    enableservice('AutomationServer') &~||<0m  
    J8? 6yd-7  
    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 &\C vrxa  
    t'm]E2/  
    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: B>a`mFM  
    1. 在FRED脚本编辑界面找到参考. >`,v?<>+  
    2. 找到Matlab Automation Server Type Library fVR ~PG0  
    3. 将名字改为MLAPP ;M4N=G Wd4

    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。 V~e1CZ(2X

    现在将脚本代码公布如下,此脚本执行如下几个步骤: Qyd3e O_  
    1. 创建Matlab服务器。 l*%voKZG  
    2. 移动探测面对于前一聚焦面的位置。 \4zvknk<  
    3. 在探测面追迹光线 hw~cS7  
    4. 在探测面计算照度 '[\%P2c)Q  
    5. 使用PutWorkspaceData发送照度数据到Matlab L)B?p!cdLT  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 X<-]./  
    7. 用Matlab画出照度数据 5\QNGRu"  
    8. 在Matlab计算照度平均值 z{!wQ~ j  
    9. 返回数据到FRED中 F<IqKgGzH
