    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。 Ja^ 5?Ar|  
    u3tZ[Y2 c  
    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: ekf$dgoR  
    enableservice('AutomationServer', true) x4a:PuqmGG  
    enableservice('AutomationServer') VFD%h }  
    |E/L.gdP7  
    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 zjX7C~h^Q  
    CidM(  
    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: \Mx JH[  
    1. 在FRED脚本编辑界面找到参考. z xZtz  
    2. 找到Matlab Automation Server Type Library r;cV&T/?  
    3. 将名字改为MLAPP Sj 3oV

    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。 #'o7x'n^

    1. 创建Matlab服务器。 GaNq2G  
    2. 移动探测面对于前一聚焦面的位置。 ?H;{~n?  
    3. 在探测面追迹光线 W5DbFSgB  
    4. 在探测面计算照度 u"VS* hSH

    6. 使用PutFullMatrix发送标量场数据到Matlab中 Fb Sa~uN  
    7. 用Matlab画出照度数据 1IA5.@G:
