    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。 LC\:xia{X  
    = DTOI  
    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: KBq aI((  
    enableservice('AutomationServer', true) cu?(P ;mQi  
        enableservice('AutomationServer') {4aY}= -Q*  
    u=}bq{  
    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 &E riskI  
    %O=V4%"m\  
    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: s [F' h-y  
    1. 在FRED脚本编辑界面找到参考. ]</4#?_  
    2. 找到Matlab Automation Server Type Library X7d.Ie  
        3. 将名字改为MLAPP hYXZ21(K#  
         -yQ\3wli`  
         nCMa$+  
    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。 NVqC|uEAF

    2. 移动探测面对于前一聚焦面的位置。 mhLRi\[c )  
    3. 在探测面追迹光线 J-\?,4mcP  
    4. 在探测面计算照度 #"8[8jyV  
    5. 使用PutWorkspaceData发送照度数据到Matlab UnWGMo?JEi  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 s P4 ,S(+e  
    7. 用Matlab画出照度数据 u 1{ym_  
    8. 在Matlab计算照度平均值 wV[V#KpX8-
