    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。 g_G?gO  
    5'@J}7h  
    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: /|t vGC.#  
    enableservice('AutomationServer', true) k^Zpb&`Hx  
        enableservice('AutomationServer') V2g,JFp&  
    0&=2+=[c  
    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 \=Af AO@

    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: `Gx"3ZUn  
    1. 在FRED脚本编辑界面找到参考. $^ (q0zR~l  
    2. 找到Matlab Automation Server Type Library 2`+?s  
        3. 将名字改为MLAPP >9a%"<(2#  
         N#@xo)-H

    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。 Kv:UQdnU[

    3. 在探测面追迹光线 B/q/sC  
    4. 在探测面计算照度 o m`r^3,

        6. 使用PutFullMatrix发送标量场数据到Matlab中 ?u"(^93f  
    7. 用Matlab画出照度数据 _55T
