    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。 WmU5YZ(mAq  
    4u} "ng   
    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: VA4>!t)  
    enableservice('AutomationServer', true) m# #( uSh  
    enableservice('AutomationServer') x:'M\c7  
    cI}qMc  
    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 `m2e *  
    ;A^0="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: yKE[,"  
    1. 在FRED脚本编辑界面找到参考. 1,cd[^`.  
    2. 找到Matlab Automation Server Type Library %ux%=@%  
    3. 将名字改为MLAPP .yz-o\,gF%

    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。 Hg)5c!F7

    现在将脚本代码公布如下,此脚本执行如下几个步骤: L<'8#J[_5  
    1. 创建Matlab服务器。 a[TR_ uR  
    2. 移动探测面对于前一聚焦面的位置。 aoNTRJ c$  
    3. 在探测面追迹光线 VAkZ@ u3'~  
    4. 在探测面计算照度 YTBZklM  
    5. 使用PutWorkspaceData发送照度数据到Matlab en\shc{R]`  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 rBBA`Ut@F  
    7. 用Matlab画出照度数据 -QH[gi{%`  
    8. 在Matlab计算照度平均值 M6(oJ*  
    9. 返回数据到FRED中 =n $@
