    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。 R>*g\}9Zh3  
    kQ~ %=pn  
    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: a!D*)z Y  
    enableservice('AutomationServer', true) "c,!vc4  
    enableservice('AutomationServer') Ra0=q4vdk  
    9k}<Fz"^.  
    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 n26>>N  
    kxh 5}eB  
    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 J-LPTB  
    1. 在FRED脚本编辑界面找到参考. PPj[;(A  
    2. 找到Matlab Automation Server Type Library n8$=f'Hgb  
    3. 将名字改为MLAPP xorTL8

    lBmm(<~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。 8?1o<8hV

    现在将脚本代码公布如下,此脚本执行如下几个步骤: |!Fk2Je,  
    1. 创建Matlab服务器。 # kEOKmO  
    2. 移动探测面对于前一聚焦面的位置。 f^?uY8<  
    3. 在探测面追迹光线 -w~(3(  
    4. 在探测面计算照度 (]XbPW  
    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 IA2GUnUhu  
    7. 用Matlab画出照度数据 uY;R8CiD  
    8. 在Matlab计算照度平均值 G?/c/rG  
    9. 返回数据到FRED中  w;+ br
