    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。 oJ`cefcWo  
    jp|1S^b  
    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: WIkr0k  
    enableservice('AutomationServer', true) =lG/A[66  
        enableservice('AutomationServer') =*Ru 2  
    VyWPg7}e  
    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 3S h#7"K3  
    m%[`NP (  
    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: l.@&B@5F  
    1. 在FRED脚本编辑界面找到参考. H){lXR/#u  
    2. 找到Matlab Automation Server Type Library '3eL^Aq  
        3. 将名字改为MLAPP N&K`bmtD  
         Trz41g  
         ~ u',Way  
    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。 vpL3XYs`

    现在将脚本代码公布如下,此脚本执行如下几个步骤: K%iA-h  
    1. 创建Matlab服务器。  HLsG<#  
    2. 移动探测面对于前一聚焦面的位置。 =&YhA}l\O  
    3. 在探测面追迹光线 D g~L"  
    4. 在探测面计算照度 {IR-g,B  
    5. 使用PutWorkspaceData发送照度数据到Matlab 71(C@/J  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 =}^J6+TVL  
    7. 用Matlab画出照度数据 w/UZ6fu  
    8. 在Matlab计算照度平均值 w(-h!d51+  
    9. 返回数据到FRED中 {j!+\neL
