    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。 xcsFODx~  
    W6)dUi :"  
    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: -aC!0O y`  
    enableservice('AutomationServer', true) Wn2Ny jX  
        enableservice('AutomationServer') _T_PX$B  
    ,o4r,.3[s  
    结果输出为1,这种操作方式保证了当前的Matlab实体可以用于通信 |:dCVd<du  
    }k4`  
    在winwrp界面,为增加和使用Matlab类型的目录库,我们需要如下步骤: 3zk:59  
    1. 在FRED脚本编辑界面找到参考. XryQ)x(  
    2. 找到Matlab Automation Server Type Library fMgcK$  
        3. 将名字改为MLAPP dCW0^k  
         X S6]C{  
         ](]*]a4ss  
    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。 nomu$|I

    4. 在探测面计算照度 )6PJ*;p-  
    5. 使用PutWorkspaceData发送照度数据到Matlab (YaOh^T:|  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 XfD z #  
    7. 用Matlab画出照度数据 u>JqFw1
