    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。 1)3'Y2N*  
    Pk;1q?tGw  
    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: 8)>4ZNXz  
    enableservice('AutomationServer', true) A2!pbeG  
    enableservice('AutomationServer') T$sm}=  
    NHcA6y$Cz  
    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 _>bk'V7  
    /9,y+"0SQz  
    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: C`-CfZZ  
    1. 在FRED脚本编辑界面找到参考. &dPI<HlM  
    2. 找到Matlab Automation Server Type Library T7|=`~  
    3. 将名字改为MLAPP Cj=_WWo

    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。 1\)C;c,

    现在将脚本代码公布如下,此脚本执行如下几个步骤: IBUFXzl  
    1. 创建Matlab服务器。 >2F9Tz,3  
    2. 移动探测面对于前一聚焦面的位置。 #ro$$I;  
    3. 在探测面追迹光线 \;iOQqv0&  
    4. 在探测面计算照度 j'OXT<n*  
    5. 使用PutWorkspaceData发送照度数据到Matlab BC5R$W. e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 BY9Z}/{j  
    7. 用Matlab画出照度数据 7{]L{j-  
    8. 在Matlab计算照度平均值 \}\# fg  
    9. 返回数据到FRED中 Dk&(QajL
