    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。 "cti(0F-d  
    'r'uR5jR  
    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: *Fq Nzly  
    enableservice('AutomationServer', true) KJ~f ~2;  
        enableservice('AutomationServer') gzuM>lf*{  
    z?cRsqf  
    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 HM<V$ R  
    j7i[z>:Y  
    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: *ZY{^f  
    1. 在FRED脚本编辑界面找到参考. v_Jp 9  
    2. 找到Matlab Automation Server Type Library m(&ZNZK  
        3. 将名字改为MLAPP O[-wm;_(=*  
         {9)LHX7dN  
         P+]39p{  
    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。 1 iE

    4. 在探测面计算照度 u(d>R5}'  
    5. 使用PutWorkspaceData发送照度数据到Matlab ;B tRDKn  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 in%+)`'nH7  
    7. 用Matlab画出照度数据 YwKY3kL  
    8. 在Matlab计算照度平均值 f9#B(4Tgi
