    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。 9|;"+jlt  
    !uoQLiH+  
    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: n!nXM  
    enableservice('AutomationServer', true) J\WUBt-M  
        enableservice('AutomationServer') A,P_|  
    6}Iu~| 5  
    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 I U Mt^z  
    c^4^z"Mo`  
    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: r)9&'m.:  
    1. 在FRED脚本编辑界面找到参考. +{qX,  
    2. 找到Matlab Automation Server Type Library 7K*\F}2)q  
        3. 将名字改为MLAPP s8/sH];  
         f{} zqCK  
         {iz,iv/U  
    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。 u]D>O$_ s

    1. 创建Matlab服务器。 M;14s*g  
    2. 移动探测面对于前一聚焦面的位置。 mKsTA;  
    3. 在探测面追迹光线 O%w"bEr)N  
    4. 在探测面计算照度 "*ot:;I  
    5. 使用PutWorkspaceData发送照度数据到Matlab *%{  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 HQpw2bdy  
    7. 用Matlab画出照度数据  AU3Ou5  
    8. 在Matlab计算照度平均值 #/UlW  
    9. 返回数据到FRED中 $O+e+Y
