    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。 ktlI(#\%  
    )C^ZzmB  
    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: ]PWK^-4P  
    enableservice('AutomationServer', true) TEQs\d  
    enableservice('AutomationServer') V$U#'G>m  
    #R2wt7vE  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 l /?Jp+]  
    jK`b6:#(,  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: (+SfDL$m  
    1. 在FRED脚本编辑界面找到参考. ?N*m2rv  
    2. 找到Matlab Automation Server Type Library RsnK B /  
    3. 将名字改为MLAPP $07;gpZt

    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。 P)7:G?OTx

    现在将脚本代码公布如下,此脚本执行如下几个步骤: qg_M9xJ  
    1. 创建Matlab服务器。 p6)Jzh_/

    3. 在探测面追迹光线 %x(||cq  
    4. 在探测面计算照度 Rr>nka)U  
    5. 使用PutWorkspaceData发送照度数据到Matlab [2h 4%{R&  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 bH 6i1c8  
    7. 用Matlab画出照度数据 :SBB3G)|
