    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。 @H?OHpJ"`  
    P}Ig6^[m\  
    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: SdlO]y9E  
    enableservice('AutomationServer', true) yT/rH- j;5  
    enableservice('AutomationServer') EcHZ mf  
    55O}SUs!P  
    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 mHMsK}=~  
    uY~mi9E  
    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: K7&]| ^M9  
    1. 在FRED脚本编辑界面找到参考. t[!,puZc#  
    2. 找到Matlab Automation Server Type Library lD$s, hp  
    3. 将名字改为MLAPP !6|_`l>G,

    {O _X/y~  
    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。 k H65k (

    现在将脚本代码公布如下,此脚本执行如下几个步骤: n/;{-  
    1. 创建Matlab服务器。 zKP[]S-  
    2. 移动探测面对于前一聚焦面的位置。 TE&E f$h  
    3. 在探测面追迹光线 9mvy+XD  
    4. 在探测面计算照度 &G%AQpDW5  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;0WAfu}#H  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 "-S!^h/v  
    7. 用Matlab画出照度数据 "#wAGlH6>  
    8. 在Matlab计算照度平均值 Ut~YvWc9  
    9. 返回数据到FRED中 )b nGZ8h99
