    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。 -t3i^&fj8  
    W`L!N&fB  
    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: \Tm}mAvK/o  
    enableservice('AutomationServer', true) T+CajSV  
    enableservice('AutomationServer') %l$W*.j|;  
    6 bO;&  
    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 qO()w

    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: 3QCVgo i\  
    1. 在FRED脚本编辑界面找到参考. $YM_G=k  
    2. 找到Matlab Automation Server Type Library ^^}Hs-{T  
    3. 将名字改为MLAPP b{&FuvQg2

    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。 (vyz;Ob

    现在将脚本代码公布如下,此脚本执行如下几个步骤: !7 _\P7M  
    1. 创建Matlab服务器。  MCnN^

    3. 在探测面追迹光线 AHd-  
    4. 在探测面计算照度 DW2>&|  
    5. 使用PutWorkspaceData发送照度数据到Matlab 5D' bJ6PO  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 D}{b;Un  
    7. 用Matlab画出照度数据 (bm;*2  
    8. 在Matlab计算照度平均值 ]QrR1Rg  
    9. 返回数据到FRED中 $p$dKH
