    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。 yKC1h`2  
    bv}e[yH  
    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: +77B656  
    enableservice('AutomationServer', true) !iW> xo  
    enableservice('AutomationServer') sA oxLI  
    mTLJajE/  
    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 @iN"]GFjS  
    OU<v9`<  
    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: 8"o@$;C  
    1. 在FRED脚本编辑界面找到参考. plM:7#eA  
    2. 找到Matlab Automation Server Type Library +9B .}t#  
    3. 将名字改为MLAPP cVDcda|PE  
    ?H eUU  
    &"^U=f@v  
    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。 &mm!UJ

    现在将脚本代码公布如下,此脚本执行如下几个步骤: 1o?uf,H7O  
    1. 创建Matlab服务器。 "6Z(0 iu:{  
    2. 移动探测面对于前一聚焦面的位置。 E@4/<;eKK  
    3. 在探测面追迹光线 z#2n+hwE  
    4. 在探测面计算照度 9T0g%&  
    5. 使用PutWorkspaceData发送照度数据到Matlab \r"gqv)^  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 zpZfsn!
