    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。 \y[Bu^tk  
    7Nd*,DV_  
    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: ]NbX`'  
    enableservice('AutomationServer', true) E]\D>[0O  
        enableservice('AutomationServer') 4}+xeGA$  
    `i=JjgG@  
    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 Z+r%_|kZ

    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: +:fqL  
    1. 在FRED脚本编辑界面找到参考. p(~Y" H  
    2. 找到Matlab Automation Server Type Library | A3U@>6  
        3. 将名字改为MLAPP $Z,i|K;  
         ||yXp2

    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)u\1AV5

    现在将脚本代码公布如下,此脚本执行如下几个步骤: a3Z :C!|O'  
    1. 创建Matlab服务器。 mfu*o0   
    2. 移动探测面对于前一聚焦面的位置。 @>M8Pe  
    3. 在探测面追迹光线 UCe,2v%  
    4. 在探测面计算照度 s.VUd R"  
    5. 使用PutWorkspaceData发送照度数据到Matlab C(EYM$  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 <\E"clZI  
    7. 用Matlab画出照度数据 kuWK/6l4  
    8. 在Matlab计算照度平均值 c:3@[nF~  
    9. 返回数据到FRED中 wy,Jw3
