    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。 y:;.r:  
    ot}erC2~  
    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: ~:DL{ZeEb  
    enableservice('AutomationServer', true) 7ch9Pf  
        enableservice('AutomationServer') W"NI^OX  
    [dJ!JT/X{  
    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 981-[ga `Y

    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: WNyW1?"  
    1. 在FRED脚本编辑界面找到参考. \,#$,dUXD  
    2. 找到Matlab Automation Server Type Library c{M ,K  
        3. 将名字改为MLAPP j, 0`k

         b>-DX  
    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。 FLi'}C

    1. 创建Matlab服务器。 _uIS[%4g  
    2. 移动探测面对于前一聚焦面的位置。 eEZgG=s  
    3. 在探测面追迹光线 0AB a&'h  
    4. 在探测面计算照度 K\K& K~Z  
    5. 使用PutWorkspaceData发送照度数据到Matlab 0m_yW$w  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 J"r?F0  
    7. 用Matlab画出照度数据 BSm"]!D8*
