    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。 }TE4)vXs  
    'qel3Fs"  
    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: 9jW/"  
    enableservice('AutomationServer', true) MG6taOO!  
    enableservice('AutomationServer') hDBVL"  
    ;U$Fz~rJ  
    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 3"afrA  
    s[6y|{&ze  
    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: }\Kki  
    1. 在FRED脚本编辑界面找到参考. Jd#g"a>zZ  
    2. 找到Matlab Automation Server Type Library #fdQ\)#q>  
    3. 将名字改为MLAPP ip.aM#

    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。 =, kH(rp2

    5. 使用PutWorkspaceData发送照度数据到Matlab o+-G@ 16  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 +2X q+P  
    7. 用Matlab画出照度数据 HYqDaRn
