    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。 `-&K~^-cH  
    b6M  
    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: }`"6aM   
    enableservice('AutomationServer', true) MW{8VH6+  
        enableservice('AutomationServer') Sc   
    Tf)*4O4@'  
    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 c"Sq~X

    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: 8Eq7Sa  
    1. 在FRED脚本编辑界面找到参考. s{" 2L{,$  
    2. 找到Matlab Automation Server Type Library go"Hf_  
        3. 将名字改为MLAPP JLi|Td "1%  
         `XB 9Mi=  
         Z/K{A`  
    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。 n(|^SH4$b

    1. 创建Matlab服务器。 f9;(C4+  
    2. 移动探测面对于前一聚焦面的位置。 Uwi7)  
    3. 在探测面追迹光线 gdoLyxQ  
    4. 在探测面计算照度 _[y/Y\{I  
    5. 使用PutWorkspaceData发送照度数据到Matlab p^_yU_  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 rbCAnwA2  
    7. 用Matlab画出照度数据 Z<4AL\l 98  
    8. 在Matlab计算照度平均值 9mFE?J  
    9. 返回数据到FRED中 PuO&wI]:
