    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。 {7q +3f <  
    G Q+g.{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: 3WdANR  
    enableservice('AutomationServer', true) .mS'c#~5Y  
        enableservice('AutomationServer') D8_-Dvp7H  
    2KmPZ&r  
    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 ) /<\|mR  
    I:#Es.  
    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: bPdbKi{j@  
    1. 在FRED脚本编辑界面找到参考. ]O;Rzq{D(  
    2. 找到Matlab Automation Server Type Library xSHeP`P^X  
        3. 将名字改为MLAPP =}AwA5G  
         d~J4&w  
         AfW9;{j&I  
    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。 4q5bW+$Xj

    2. 移动探测面对于前一聚焦面的位置。 (Sg52zv  
    3. 在探测面追迹光线 APksY!  
    4. 在探测面计算照度 DV/P/1E  
    5. 使用PutWorkspaceData发送照度数据到Matlab FLekyJmw~  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 OW<5,h  
    7. 用Matlab画出照度数据 V qW(S1w  
    8. 在Matlab计算照度平均值 A5ps|zidI
