    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。 OrqJo!FEg{  
    h,RUL  
    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: #j ~FA3O  
    enableservice('AutomationServer', true) ucm.~1G(  
    enableservice('AutomationServer') ff+9(P>*  
    >[3,qP]E  
    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 =;?PVAdu%#

    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: =D:R'0YH  
    1. 在FRED脚本编辑界面找到参考. uL{~(?U$  
    2. 找到Matlab Automation Server Type Library Bv|9{:1%X}  
    3. 将名字改为MLAPP *,=+R$

    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。 \:)o'-

    2. 移动探测面对于前一聚焦面的位置。 wjGjVTtHs  
    3. 在探测面追迹光线 <$Kv^Y*  
    4. 在探测面计算照度 ZN]c>w[ )I  
    5. 使用PutWorkspaceData发送照度数据到Matlab 9Q5P7}%p  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 ?01""Om   
    7. 用Matlab画出照度数据 a/`Yh>ou  
    8. 在Matlab计算照度平均值 NqfDY  
    9. 返回数据到FRED中 UE;) mZ=l|
