    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。 V_n tS& 2o  
    X Vo+ <&  
    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: 4? rEO(SZ  
    enableservice('AutomationServer', true) c@nh>G:y{&  
        enableservice('AutomationServer') J!3;\  
    utn,`v   
    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 $S2 /*  
    #i*PwgC%_  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: |942#rM  
    1. 在FRED脚本编辑界面找到参考. bTAY5\wB  
    2. 找到Matlab Automation Server Type Library Yn?Xo_Y  
        3. 将名字改为MLAPP ]ab q$Y'

    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。 J*6B~)Sp@

    1. 创建Matlab服务器。 8|L5nQ  
    2. 移动探测面对于前一聚焦面的位置。 +Oo-8f*  
    3. 在探测面追迹光线 Pj BBXI1i  
    4. 在探测面计算照度 jzWgyI1b  
    5. 使用PutWorkspaceData发送照度数据到Matlab j>.1RG  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 uFlf#t =  
    7. 用Matlab画出照度数据 &wu1Zz[qcz  
    8. 在Matlab计算照度平均值 )U]q{0`  
    9. 返回数据到FRED中 PTXS8e4
