    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。 A5Qzj]{ba  
    0e^j:~*  
    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: G0^WQQ4  
    enableservice('AutomationServer', true) 4~53%=+  
    enableservice('AutomationServer') G9<p Yt{:  
    xO`w| k  
    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 `^-?yu@

    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: vtc} )s\  
    1. 在FRED脚本编辑界面找到参考. !Ui3}  
    2. 找到Matlab Automation Server Type Library A=o p R  
    3. 将名字改为MLAPP :CV!:sUm

    R0(Nw7!d/[  
    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。 :@I?JSi

    现在将脚本代码公布如下,此脚本执行如下几个步骤:  L,!Z  
    1. 创建Matlab服务器。 X4>c(1e  
    2. 移动探测面对于前一聚焦面的位置。 N'+d1  
    3. 在探测面追迹光线 $NJ]2P9L  
    4. 在探测面计算照度 J6;^:()  
    5. 使用PutWorkspaceData发送照度数据到Matlab I1=YSi;A  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 hun L V8z  
    7. 用Matlab画出照度数据 c|x:]W'ij  
    8. 在Matlab计算照度平均值 E1_FK1*V;  
    9. 返回数据到FRED中 *,-)4)7d
