    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。 *Z}^T:3iw}  
    v~E\u  
    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: LX f r  
    enableservice('AutomationServer', true) h,-2+}  
    enableservice('AutomationServer') :&SvjJR  
    ^97u0K3$  
    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 Ao?y2 [sE  
    QAGR\~  
    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: /B"FGa04p(  
    1. 在FRED脚本编辑界面找到参考. @}9*rWJIE  
    2. 找到Matlab Automation Server Type Library c{.y9P6  
    3. 将名字改为MLAPP 1. A@5*Q  
    rtM29~c>@  
    9;2{=,  
    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。 E>LZw>^Y J

    4. 在探测面计算照度 Oq3aboAt  
    5. 使用PutWorkspaceData发送照度数据到Matlab 7QSr C/e  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 I{nrOb1G(  
    7. 用Matlab画出照度数据 .)(5F45Wg  
    8. 在Matlab计算照度平均值 hW<TP'Zm*
