    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。 y|lP.N/  
    ?_tOqh@in  
    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: +ubO-A?  
    enableservice('AutomationServer', true) ^OQ_iPPI  
    enableservice('AutomationServer') T+.wJ W:jh  
    3IJIeG>  
    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 $x2<D :

    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: pxY5S}@  
    1. 在FRED脚本编辑界面找到参考. -#Wc@\;  
    2. 找到Matlab Automation Server Type Library ;hZ(20  
    3. 将名字改为MLAPP < )?&Jf>_

    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。 { _ 1q`5o

    现在将脚本代码公布如下,此脚本执行如下几个步骤: }h]:I'R!  
    1. 创建Matlab服务器。 bC@b9opD  
    2. 移动探测面对于前一聚焦面的位置。 R0=/ Th -  
    3. 在探测面追迹光线 om/gk4S2  
    4. 在探测面计算照度 <QJmdcG  
    5. 使用PutWorkspaceData发送照度数据到Matlab `iY)3Rq  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 b<7.^  
    7. 用Matlab画出照度数据 i2!{.*.  
    8. 在Matlab计算照度平均值 iL\\JuY  
    9. 返回数据到FRED中 Ugs<WVp$
