    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。 X6dv+&=?  
    7!E?(3$#"  
    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: :9`T.V<?  
    enableservice('AutomationServer', true) /hMD Me  
    enableservice('AutomationServer') /)` kYD6  
    *OQr: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 &zYo   
    ?#LbhO*   
    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: &<E*W*b[  
    1. 在FRED脚本编辑界面找到参考. $}/ !mXI5  
    2. 找到Matlab Automation Server Type Library R)w|bpW  
    3. 将名字改为MLAPP Gq/f|43}@O  
    93npzpge  
    'B>%5'SdD  
    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。 Z) zWfv}

    3. 在探测面追迹光线 89@e &h*  
    4. 在探测面计算照度 |QvG;{!  
    5. 使用PutWorkspaceData发送照度数据到Matlab e:Zc-  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 A qKl}8  
    7. 用Matlab画出照度数据 I9`R L Sn  
    8. 在Matlab计算照度平均值 DVNGV   
    9. 返回数据到FRED中 =;/4j'1}9
