    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。 tag)IWAiE  
    [ s/j?/9  
    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: Y#):1C1  
    enableservice('AutomationServer', true) )s7EhIP  
    enableservice('AutomationServer') lp d~U2&  
    ;[lLFI  
    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 8WLh7[  
    L4+R8ojG  
    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: AvIheR  
    1. 在FRED脚本编辑界面找到参考. P5dD&  
    2. 找到Matlab Automation Server Type Library ku57<kb  
    3. 将名字改为MLAPP =|O]X|y-lZ

    #WUN=u   
    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。 L kafB2y

    现在将脚本代码公布如下,此脚本执行如下几个步骤: "AqLR  
    1. 创建Matlab服务器。 q}'<[Wg

    4. 在探测面计算照度 cWQ &zc  
    5. 使用PutWorkspaceData发送照度数据到Matlab (.z0.0W  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 a{;+_J3S  
    7. 用Matlab画出照度数据 vGH]7jht
