    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。 &!EYT0=>p  
    Y8xnvK*  
    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: B*?PB]  
    enableservice('AutomationServer', true) g.sV$.T2K  
    enableservice('AutomationServer') ,$(v#Tz  
    :^L]Da3  
    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 x!Y@31!Dy

    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: _+Kt=;Y8  
    1. 在FRED脚本编辑界面找到参考. )h!l%72  
    2. 找到Matlab Automation Server Type Library 1X}Tp\e  
    3. 将名字改为MLAPP wLp t2b8S

    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。 3jVm[c5%]

    1. 创建Matlab服务器。 ~F6gF7]z

    4. 在探测面计算照度 ._nKM5.  
    5. 使用PutWorkspaceData发送照度数据到Matlab IbaL.t\>  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 R}26"+~  
    7. 用Matlab画出照度数据 ,DO mh<b  
    8. 在Matlab计算照度平均值 dct#E CT
