    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。 CL5u{i5  
    />S=Y"a/7  
    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: Y.Na9&-(  
    enableservice('AutomationServer', true) U< |kA(5  
        enableservice('AutomationServer') B8NOPbT  
    yk5-@qo  
    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 Xhe25

    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: <v&>&;>3  
    1. 在FRED脚本编辑界面找到参考. 0.4c|-n  
    2. 找到Matlab Automation Server Type Library @]" :3  
        3. 将名字改为MLAPP r3<yG"J86

         |d?0ZA:z  
    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。 ,~w)~fMb8

    2. 移动探测面对于前一聚焦面的位置。 tRZCOEo4  
    3. 在探测面追迹光线 ;>{B K,  
    4. 在探测面计算照度 !run3ip`Z  
    5. 使用PutWorkspaceData发送照度数据到Matlab m7Nm!Z7  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 w&:"x@ -|  
    7. 用Matlab画出照度数据 "yxIaTZu  
    8. 在Matlab计算照度平均值 N%'=el4L
