    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。 TRku(w1f  
    k?qd -_sC  
    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: on)$y&lu  
    enableservice('AutomationServer', true) Nj$h/P  
    enableservice('AutomationServer') y({EF~w  
    "Is0:au+?}  
    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 +~!\;71:f  
    Rd>PE=u  
    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: ibv.M=  
    1. 在FRED脚本编辑界面找到参考. *S] K@g  
    2. 找到Matlab Automation Server Type Library #ByrX\  
    3. 将名字改为MLAPP ~.&2N Ur  
    /rZ`e'}

    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。 fSw6nEXn

    1. 创建Matlab服务器。 (sL!nRw

    3. 在探测面追迹光线 prCr"y` M  
    4. 在探测面计算照度 7$|L%Sk

    7. 用Matlab画出照度数据 wH0Ks5
