    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。  JaY"Wfc  
    ^-Od*DTL  
    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: DRQx5fgL  
    enableservice('AutomationServer', true) h`|04Q  
        enableservice('AutomationServer') mF*x&^ie  
    tNT Sy =  
    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 en< $.aY  
    06pvI}   
    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: bGWfMu=n  
    1. 在FRED脚本编辑界面找到参考. l\s!A&L  
    2. 找到Matlab Automation Server Type Library X@`a_XAfd  
        3. 将名字改为MLAPP p' >i3T(  
         W91yj:  
         GF ux?8A:%  
    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。 lv 8EfN

    1. 创建Matlab服务器。 uNzc,OH  
    2. 移动探测面对于前一聚焦面的位置。 dgw.OXa  
    3. 在探测面追迹光线 +& r!%j7  
    4. 在探测面计算照度 n"EKVw7Y  
    5. 使用PutWorkspaceData发送照度数据到Matlab $6"(t=%{  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 F^O83[S  
    7. 用Matlab画出照度数据 ~gfR1SE  
    8. 在Matlab计算照度平均值 D!&(#Vl _  
    9. 返回数据到FRED中 6TW7E }a.
