    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。 Z.LF5ur  
    ,TO&KO1;&  
    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: cmh/a~vYaY  
    enableservice('AutomationServer', true) .+AO3~Dg  
        enableservice('AutomationServer') m4P=,=%  
    j1toV$)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 _jb"@TY  
    sXC]{] P  
    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: kqAQrg]n  
    1. 在FRED脚本编辑界面找到参考. HNoh B4vt  
    2. 找到Matlab Automation Server Type Library DPtyCgH  
        3. 将名字改为MLAPP .J\U|r  
         ~h[lu^ZSi  
         5p{tt;9[  
    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。 !"J*

    2. 移动探测面对于前一聚焦面的位置。 |V~P6o(/  
    3. 在探测面追迹光线 B&Ci*#e  
    4. 在探测面计算照度 <db/. A3

        6. 使用PutFullMatrix发送标量场数据到Matlab中 fW}H##b  
    7. 用Matlab画出照度数据 :~)Q]G1Nj
