    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。 xG<H${ k;  
    =J.)xDx*  
    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: T:0X-U  
    enableservice('AutomationServer', true) @+",f]  
    enableservice('AutomationServer') )>LQ{ X.  
    &J|3uY,'j  
    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  9H*$3

    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: dN>XZv  
    1. 在FRED脚本编辑界面找到参考. UTQ$sg|7p  
    2. 找到Matlab Automation Server Type Library cOUsbxYTD  
    3. 将名字改为MLAPP fys@%PZq

    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。 -@ #b<"1

    现在将脚本代码公布如下,此脚本执行如下几个步骤: /vPh_1  
    1. 创建Matlab服务器。 dQ^>,(

    3. 在探测面追迹光线 c1wM"  
    4. 在探测面计算照度 wgSA6mQZ  
    5. 使用PutWorkspaceData发送照度数据到Matlab ]+[ NX)=  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 JnCY O^Qj  
    7. 用Matlab画出照度数据 [(tgoh/  
    8. 在Matlab计算照度平均值 w5jH#ja  
    9. 返回数据到FRED中 UuxWP\~2
