    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。  "LB MYZ  
    Rmmu#-{Y  
    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: Jg=!GU/::  
    enableservice('AutomationServer', true) b;jdk w|  
    enableservice('AutomationServer') o 7kg.w|  
    SZe55mK`  
    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 V5ZC2H  
    RN-gZ{AW  
    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: nQOdM#dP  
    1. 在FRED脚本编辑界面找到参考. vwu/33  
    2. 找到Matlab Automation Server Type Library HBe*wkPd  
    3. 将名字改为MLAPP -)(=~|,Pq/

    r9{@e^Em  
    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。 Nf!N;Cy?

    4. 在探测面计算照度 ,L-/7}"VHA  
    5. 使用PutWorkspaceData发送照度数据到Matlab ?&wrz  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 oH6zlmqG"  
    7. 用Matlab画出照度数据 td7(444]  
    8. 在Matlab计算照度平均值 &J2 UAmB
