    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。 <OH{7>V  
    2LfiaHO  
    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: Hs:0j$  
    enableservice('AutomationServer', true) SFu]*II;{  
    enableservice('AutomationServer') xzi_u.iOP  
    L< XAvg  
    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 /^]/ iTg  
    _:N=  
    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: ,.kJF4s&  
    1. 在FRED脚本编辑界面找到参考. eA{ nwtN  
    2. 找到Matlab Automation Server Type Library mjQZ"h0  
    3. 将名字改为MLAPP ) $`}~

    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。  /!#A'#Z

    5. 使用PutWorkspaceData发送照度数据到Matlab e# U@n j6  
    6. 使用PutFullMatrix发送标量场数据到Matlab中 )x,/+R]{8l  
    7. 用Matlab画出照度数据 J$W4AT

    9. 返回数据到FRED中 SK5_^4
