    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。 XpU%09K  
    r\DA&b  
    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: ~Ddlr9Ej  
    enableservice('AutomationServer', true) #Z>EX?VS:  
        enableservice('AutomationServer') vo JmNH  
    Nr#" 5<W  
    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 ~gJJ@j 0n  
    o"-*,:Qe  
    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: |;k@Zlvc  
    1. 在FRED脚本编辑界面找到参考. HH3Ln+AWg_  
    2. 找到Matlab Automation Server Type Library w_lN[u-L  
        3. 将名字改为MLAPP "[t b-$ER  
         A-om?$7  
         1NQstmd{  
    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。 ~|5B

    4. 在探测面计算照度 HyKv5S$  
    5. 使用PutWorkspaceData发送照度数据到Matlab wseb]=U  
        6. 使用PutFullMatrix发送标量场数据到Matlab中 a15kFun  
    7. 用Matlab画出照度数据 1K&l}/zUl
