    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。 ntT~_Ba8;u  
    U~e^  
    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: zxt&oT0Q  
    enableservice('AutomationServer', true) P6cc8x9g(  
    enableservice('AutomationServer') Ni4*V3VB  
    (}C%g{8  
    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 %7*Y@k-)o  
    >nL9%W}8M  
    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: 9 O/l{  
    1. 在FRED脚本编辑界面找到参考. ?NL>xMA  
    2. 找到Matlab Automation Server Type Library ird q51{G  
    3. 将名字改为MLAPP :6Q`! in

    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。 ja2PmPv

    5. 使用PutWorkspaceData发送照度数据到Matlab z!={d1u#T  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 *qLOr6  
    7. 用Matlab画出照度数据 lTh}0t  
    8. 在Matlab计算照度平均值 O!(FNv0
